Yeah I think roundabouts will be the last to be implemented. Some of the crazier ones are hard problem for humans, let alone AI.

I haven't noticed that the car recognises speed limit signs - it all seems to be done by GPS data, which is odd considering Elon's sensible view of autopilot using camera view rather than GPS data.
There are almost no roundabouts in the US. Read into that what you will.
If I were a betting man..... I'd bet that the system is technically capable of reading road signs but that Tesla have run into Patent / Contract / Licencing issues with the Mobileye system they used previously (AP1). That can read road signs on AP1, and all the other cars it's fitted to....
The Mobileye patent is pretty specific - more than one way to skin a cat so to speak.
I think Tesla were playing catchup after Mobileye split and it was easier/quicker to do the GPS solution as a stop gap and let a more flexible visual solution fall out in the wash later, possibly to augment the GPS system and hopefully, one day, a v2i solution - connected to infrastructure.
Lots of roundabouts in rural Arizona where I live. No electricity to power lights in many areas. This is the Wild West! Just got back from 3 weeks in UK driving an Audi A4. I hated that car compared to my M3. And yes, particularly for Yanks like myself, roundabouts with 6 or 8 exits are a challenge and I'll be amazed if technology ever handles them properly.

They are one way roads with junctions all on one side, looped back onto themselves and, for me, one of three simplest types of junction that exist.
What is your distance setting set to and what was your speed when it "accelerated wildly"? I find that when I am slow stop and go traffice, it works best when it is set to 3 and then at faster highway speeds I set it to 4. I don't experience any wild accelerations any more.I've only had a test drive in an M3 so far. For me, ap was great on the motorway but, when I tried to engage TACC on a normal road it scared the **** out of me by accelerating wildly towards the car in front and a sharp corner (I was doing about 20 in a 30 zone at the time). I'm not looking forward to learning it's foibles....
I'd love it to have a dumb cruise option, or at least an option to engage at the current speed (or even just accelerate gently rather than full power)! It seems ridiculous that it engages at what it thinks is the posted speed limit.
As for roundabouts, I've never understood why people have such a problem with them. They are one way roads with junctions all on one side, looped back onto themselves and, for me, one of three simplest types of junction that exist.
I don't really like AP and wouldn't pay for it again if / when I replace this car. Its not to be trusted and you need to watch it like a hawk ready to catch it when it lunges off the lane or slams on the brakes for a random shadow
