I think Pirelli and Michelin will like to know this one as will half of the experts in physics!
In racing, there is something called Marbles. Now this is debris, typically rolled chucks of rubber thats peeled off tyres on a race track, but on the open road, this will typically be aggregate, chunks of stone that has been released from the road surface.
You find this on the edges of roads or on the outer edge of roundabouts.
These are an absolute nightmare to drive on, but if you have a lightweight car you can drive on these parts of the roundabout fast enough to undertake people who cut across to the inner lane of the roundabout, even in the wet.
I would not dare attempt that in an EV, the car would just just slide off the road. I dont care for the lower center of gravity that much, in fact if its too low it starts to affect the suspension and handling, where the suspension hits the bump stops.
Front wheel drive diesels have this problem over the front axle, where their suspension bottoms out on the bump stops.
There really are some right royal nutters living here, thats why I hope the porsche night vision system can record these events besides showing up on the dashboard.
Ok, hold up. You have:
1. roundabouts, ok, no problem, we have lots of those, I've never had a problem in an EV.
2. Gutter curbs around roundabouts. Yes driving in those is bad, you'll get a flat tire pretty quickly that way (no matter your car). I used to ride my bike in those and got flats all the time.
3. You want to race around other people in the round about. Ugh, this isn't the USA is it? I'm guessing Russia or China, or some other developing world country?
I think this is a niche case, like doing donuts or drifting.
