Are they? I hadnt noticed. I suspect its down to observer bias. Easier to
see a rearward facing camera when your following or stopped in traffic than
a forward facing one when youre looking in your mirror or looking at
traffic approaching.

Confused?
Do you mean cameras that allow you to see out the back, whilst
reversing or such, that allows you a 'better', clearer might be a better
word, to the rear than simply looking out the back window. Especially
trying to reverse into tight spots (though only an aid [1] really, you
should also keep an all round check on environs).

Looking forward is usually the way you perceive the world and with front
steer cars all is as expected. If you need evidential views to the
front of the car a dashcam can be fitted.

[1] I was taught that even with a reversing cam you should mainly look
out the back window and glance in the mirrors (this also lets you check
any front end swing) and only use the rear view as an AID to ensure you
fit (I had a habit of staring at the rear view screen, soon gotten out
of me ).

The cameras on my car are mostly unobtrusive. One reversing one where the
boot handle used to be. One forward facing in the radiator grille. And
one built into the rear view mirror housing on the windscreen.

The only easily visible one is the dashcam.

Dashcams point forwards as do cameras used to recognise road signs and
perhaps those used to warn of lane discipline.

Rear facing cameras are used for (auto) reverse parking aids and/or to
give a greater view than an internal rear view mirror.

I wonder what they are thinking when they sit in lane 2 (at 60 mph)
all the time when the rest of the motorway is empty (seriously)?

Is it I wonder that they are less likely to get taken off the motorway
by mistake, like they might if L1 turns off at a junction (and they
miss all the clues) or that they think it's just for lorries?

I've sat behind them (at a safe distance) and they have (sometimes)
eventually pulled into L1, I overtake and go back into L1 myself, only
to see them go back out into L2 (now moving slower than I am in L1)?

Dad was party to the nearest thing you could get to your laser canon,
but for tailgaters.

4 of them were driving back from a studio photo session down a winding
country road and whilst making good progress themselves, someone was
stuck on their tail for some reason. After a few miles of that, one of
the guys in the back put a Mecablitz studio flashgun on the parcel
shelf, facing backwards and switched it on. On a suitably safe
straight bit, he fired it and they watched the offending headlights
disappear backwards very fast, as might happen if someone had braked
fairly hard because they had temporarily lost their night vision. ;-)

Must say, most people in my current neck of the woods leave a reasonable gap. Just the odd one gets too close and stays there. When they do, you can be pretty sure that they are also going to try to zoom past when they can. Last really bad one tried to do so and went into a hatched area for people turning right from the oncoming lane. Shame someone turned into it right in front of them. Screeching brakes, sudden dive in front of me with inches to spare. (I was doing spot on 60 so any overtaking was automatically speeding.)

We have seen so many "If you can read this, you are too close" signs (and many variants). Am a bit surprised I haven't yet seen automatic signs that light up on the back of the vehicle being tailgated. OK, so they might well be illegal, but that doesn't stop much else.

Best for what? If its for recording incidents its not really a question
of €œor€� but €œfront or front + rear€�. I doubt many folk just have a rear
facing camera for recording incidents.

As to the best camera, I havent a clue as I dont have one. I have tried
a cheapie from eBay that claimed to be HD but it was rubbish. Check reviews
carefully rather than relying on claimed spec when buying.

They can also give an indication of where the car is going to go using
lines of various colours.
Only if its got inputs from the steering though, this is why
manufactures cameras cost more as they need a screen and other sensors
to do the full job.

Is it I wonder that they are less likely to get taken off the motorway
by mistake, like they might if L1 turns off at a junction (and they
miss all the clues) or that they think it's just for lorries?

I think it's more that they want to go faster than lorries at 56 in Lane1,
and don't want to have to keep swapping between L1 and L2 every time they
meet a lorry, with the risk that they may get "trapped" in L1 by cars in L2
which won't keep enough gap from the car ahead of them to allow a vehicle to
join from L1.

I tend to drive at about 70 (I'd go at 80 if the law allowed it) and on a
motorway that has a lot of slower lorries, I mainly use L2, rarely going
into L1 except when there is a long gap to the next lorry. On a motorway
where L1 is generally going at 70, I stay in L1.

My general rule is: if traffic is going at within a couple of mph of what I
want to do, I stay put behind so as not to clog up the next lane, and if I
do move into the next lane, I aim to be doing at least 5 mph faster than the
traffic I'm overtaking. I try hard to avoid travelling at the same speed as
the vehicle my left.


I wonder whether speed limiters on lorries in the UK will tend to be
adjusted up to 60 mph (the UK limit for HGVs over 7.5 T) rather than 56 mph
/ 90 km/hr, after Brexit. No doubt foreign drivers from the EU will continue
to have their limiters at 56 but UK lorries that don't go abroad won't need
to comply.

https://en.wikipedia.org/wiki/Road_s...United_Kingdom
(section "Speed Limiters") says that at present limiters are set at round
numbers of km/hr - so coaches are allowed to go at up to 70 mph on motorways
but are required to be speed-limited to 62 mph / 100 km/hr.

Are they? I hadnt noticed. I suspect its down to observer bias. Easier
to
see a rearward facing camera when your following or stopped in traffic
than
a forward facing one when youre looking in your mirror or looking at
traffic approaching.

My observation is that far more cars have front cameras that rear ones, and
the most cars that have rear ones also have front ones. But as you say
observer bias plays a big part.

We should get a rear camera - and a socket-doubler so it can be powered at
the same time as the coolbox which we tend to keep in the boot (though not
always turned on) in case we want to transport frozen or chilled shopping.

Windscreen one is on the inside and the wipers clear that area.

The other two just seem to be OK. I probably have to clean each once

The rear one on our Honda CR-V seems to get *very* dirty, *very* quickly. If
I need to reverse into a confined space where there is a central obstruction
(eg a bollard) that cannot be seen by either door mirror or the rear-view
mirror (the situation where a reversing camera is invaluable) then I often
have to get out before reversing to wipe the dirt off the lens, otherwise
all I see on the screen is a uniform featureless grey blur. They really
could have done with a small wiper (or even just a jet of water) that
operates with the rear wiper or washer.

I've learned not to trust parking sensors on their own, after both my wife
and I nudged bollards which hit the bumper right on the parking sensor - I
wonder whether the parking sensors on the CR-V can see either side but not
directly in front of the sensor.

My impression is that modern cars (Peugeot 308, Honda CR-V) seem to suffer a
lot more from dirt sticking to the rear end (rear window, tailgate, bumpers)
than happened with my older Peugeot 306s and VW Golfs (Mark 2 and Mark 3).
