It's crazy how fast a car can be when you aren't required to weigh it down with a bunch of stuff to meet road safety standards. That SU7 Ultra would be considerably heavier (and slower) with all the things they'd need to add to it to meet US safety laws.
If you took any of the 3 cars in this pic
>>28527881and stripped out all the safety equipment that the SU7 doesn't have, they would probably end up being faster than it is.
But then of course you'd have autists and trolls screeching about how their times are invalid because they're not street legal so that they could keep the argument going.
The bottom line is that equipment would either have to be added to the SU7 or be removed from the other cars for a legitimate performance comparison to be made between them.
