I've read that with the previous cars there were too many contacts between them, because they were very strong and could take it. So the organizers asked the manufacturer to make the front wing more brittle, so that if you drive too recklessly you break it !
It is true. There is a lot of contact between the cars, and this is normal. And in a way this is allowed.
The cars of the first generation, had to be more resistant, because it took two cars per driver to complete the race. So the cars had to be very sturdy, to stand the race.
Second generation cars, already have battery for a complete race and therefore, do not need as much resistance.
Even so, the cars continue to be very resistant, because of the type of track they race on.
Next to the road is the wall. Therefore, for the safety of the drivers, the cars must be more resistant.
Of course, then the pilots take advantage of this, to get as much silver as possible.
