There is a big difference between the laminated screens in cars and
laminated glass you buy in sheets.

Car stuff is toughened and then laminated.

Really? How does it manage to crack, then?

Sharp edges of stones usually.

Laminated glass is float glass laminated and is not toughened at all.
If it were toughened you couldn't cut it to size.

There is nothing to stop you using toughened laminated glass for
furniture other than the cost.
You will find that toughened laminated glass is used in places like
escalators if you look.

I can see that - where both maximum resistance to impact and it retaining
strength if broken is needed. But don't think this applies to car screens.

It does actually.

smeared fly splat that isn't... The auto doesn't cancel when you
switch off, but static snow frost doesn't trigger 'em. The heated

Mine come on a little before I'd think, "hum ought to turn the lights
on",

Surely that's adjustable?

And do they have two brightnesses, where you turn on sides, then dips?

so they stay in auto, unless the hill fog is getting a bit thick
and I switch dipped off and just use the front fogs. Far less glare,
not much reach but then visibilty will be down to only a few tens of
yards anyway.

What they will do is switch off in bright daylight fog! Ok there is a
light on the instrument panel but if you're concentrating on what's
outside. I wish it would "bong" when ever it changes the state of an
indicator lamp. Ideally "bong" for pay attention and "bing" for
happy.

It's not as if it has a shortage of bongs. It'll use them with gay
abandon if the car is moving and your seatbelt isn't fastened, a door
is open and engine running and/or lights left on.

If it's bright daylight, the fog isn't thick enough to see lights. What distance of visibility do you have at that point?

I've had two different makes with rain sensing wipers. Both I'd guess with
Bosch systems being German cars.

Neither works perfectly in town. Too much a build up of rain on the screen
before they wipe. I end up using the single wipe function they both have.

Are you certain your works after switching off the engine? If it is always
'ready' if the stalk is left in the auto position, it would come on when
say using a car wash. Which might just remove the wipers.

Then turn it off before entering, there's probably a warning sign on the wash.

Silly to make something car wash proof and ruin its everyday use.

Many cars allow that, most owners never read the manual to know how.

On a corsa you hold the stalk down for as long as you want between wipes
and it remembers that. Easy if you know how.

I've had it on two cars, and both were obvious that they were there. A twist switch on the wiper stalk.

Some glass seems to be indestructible on the large surface, but if you tap the corner of it (not in a frame), it falls to bits.

Can't really think why not, other than the slight risk that as
laminated will break into shards that may detach from the plastic
layer it poses a bigger risk than the (still piggin' sharp) bits that
toughened fails to.

Snow just puts a strain on the motor. The problem is when the rubber is frozen to the screen.

Fairly new car so has DLRs. The DLRs are brighter than the sides and
come on when you switch the lights to "off" or "auto" with a high
light level. With low light level the DLRs are switched off and
headlights on, but in the state they where last used, (dipped/main).
Being rural if I arrive home at night I'll be on main beam...

The side light position switches the DLRs off and sidelights on.

If it's bright daylight, the fog isn't thick enough to see lights. What
distance of visibility do you have at that point?

I've not driven in daylight fog since the occasion that the damn
thing silently switched the lights off(*). Well switched to DLRs at
the front but switched the rear lights and rear fogs off. IIRC
visibilty was such that dipped head lights and rear lights should
have been on. This was on a quiet motorway, rear fogs a good idea, so
the wazzocks doing 70 plus have as much chance as possible of seeing
me... (yes I do know how to switch them off and do so when visibilty
is reasonable and/or there is some one following me).

Well clearing the snow from the screen last week they came on
automagically when I pushed the snow off and water blobs were left.

If it is always 'ready' if the stalk is left in the auto position, it
would come on when say using a car wash.

They would, see the comment about them coming on with a fly splatted
screen...

Of course even the earlier intermittent wipe isn't perfect. Needs a
different interval depending on how light the rain is.

I think her indoors Fiesta had a sort of "learning" intermittent.
With the switch in "intermittent" it remembered the interval between
manual uses of the single wipe.

How absurd that personal preference for lighting is not included. What's the chances of its setting being anything like what you want?

come on when you switch the lights to "off" or "auto" with a high

headlights on, but in the state they where last used, (dipped/main).
Being rural if I arrive home at night I'll be on main beam...

If I get a car with DRLs, the first thing I'll do is disable them. Shining bright lights at people when it's broad daylight is beyond stupid. It does not make you more visible, it just distracts people.

The side light position switches the DLRs off and sidelights on.

If it's bright daylight, the fog isn't thick enough to see lights. What
distance of visibility do you have at that point?

Both the cars I've had with rain sensing wipers have an adjustment switch

Snow just puts a strain on the motor. The problem is when the rubber is
frozen to the screen.

Even if they are by the time the frost has melted to water blobs that
the sensor sees as "rain" the blades won't be frozen to the screen.
They might still be encased in ice but the ice/glass bond will be
very weak.
