Why are they mostly rear pointing? I would have thought that it would be
better to have them pointing where you are going. |

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. |

In addition to which, I have a rear facing reversing camera, which displays on the big ICE screen in the centre dash when reverse is selected, plus reverse sensors. Rear window is high and a narrow slit, obstructed by rear headrests - the only useful mirrors are the door mirrors, so I felt the reversing camera was essential for safety. |

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. |

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. |

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). |
