Which is exactly as it should do; the speed limit changes at the speed limit sign, not at whatever point afterwards you decide to slow down to the new limit.

E-Tron reads ahead so you are down to the limit as you enter it.

Thanks

Yes, should do. I'm curious if they do do, or if they're doo-doo.

Nope. It's one of Mik's polls. Brand new only. Ferrari or Dacia and both have speed limiters (that actually work for sake of argument).

Ferrari bankrupt in a matter of months.

Cool! I’ll buy a 12Cilindri for £25k, to help them out plus it’s worthless now really

My Audi’s predictive cruise control reads speed limits. It often seems to go back to its database though. There’s one long 40 limit on an A-road near us where it decides to slow down to 30 for a second then realises it’s still 40 so speeds up again. No signs to misread.

The A329 into Reading is a dual carriageway with a bend that has a 50mph sign; I was following a Tesla M3 at just under 80 that suddenly jammed on its brakes and slowed. Driver indicated, pulled over and wave apologies to everyone who then overtook him.. will cause more issues than it solves

Same situation here https://maps.app.goo.gl/KzthLSDCx7X1hd4n9

A3 is 50 mph in this section, road running parallel is 30. Model 3 will brake to 30 mph. Loads of roads like that on the outskirts of London.

The best solution is to just put a blanket 20 mph limit across every road in the country. No confusion. No deaths.

I'm reminded of my Audi misreading the vandalised 20mph sign in the Welsh valleys as 80mph and giving it some beans unexpectedly

Tried the A-road I mentioned this morning; I put the predictive cruise control on but turned off the lane keeping because it doesn't like some of the tighter bends. I was going the opposite way to my regular 30mph hard braking moment and instead it decided that the limit was briefly 60mph (past a 50mph repeater sign) before then slowing me for the upcoming 40 limit. Definitely not misreading signs; there's clearly an underlying database which it reverts to occasionally but I'm not sure what triggers that.

Anyway, if speed limiters work based on the same tech then god help us.

My focus has the tech in, and that’s 4 years old so it’s nothing new. It comes up on the little screen in the middle of the dials, and flashes a speed limit sign when you go over the limit. I’d say it’s about as reliable as the other systems commented on here, it’s right only 75-80% of the time- it does tell you the limit is 30 in a 60/70 zone


I disagree with most of these systems- rather than making roads safer I think they’re having the opposite effect, and makes it easier to drive distracted, and the systems are the only reason the statistics say they’re better- they’re becoming essential by compensating for worse drivers

See also black boxes- yes they stop young ones driving like looneys but kids don’t learn the limits of a vehicle with a 75hp engine anymore. They learn in their first quickish car once they can get insurance without a box, so end up loosing control at 60/70/80 instead of 35mph

E-Tron is in to have the SOS system "repaired" (ie plugging back in whatever connector that was left unplugged when the front lekky motor was replaced), and mrs mik reports that her courtesy car (a small Audi of some sort - I didn't pay much attention) bings like a barsteward persistently if you are over (what it believes at that time to be) the speed limit.

Does it do the thing where you have to force the accelerator down for a few seconds so it then accelerates past the speed limit?

Don't know - I didn't drive it. I shall ask her, but I suspect she won't know either.....

BYD does that.

BYD does that.

Is it only once and then it disables it for the rest of the drive or does it do it each time?

I only took it for one drive and didn’t turn it off, so no idea!

Haven't looked around to verify this article, but it claims UK isn't taking this legislation on (not that it matters, we'll still get the vehicles with the ISA fitted presumably)

https://uk.motor1.com/news/725346/speed ... eu-not-uk/

Please let this be true.

Then I bet manufacturers would ask for some money to have it disabled, which is well worthwhile.

Dave!

My new car was registered at the end of last week so doesn’t have a limiter. It has the beep. There is a single button to press once to turn it off. I’m getting used to the muscle memory already.
