I think I read somewhere the rims are open in new cars, only the 3d renders had them closedi don’t like the closed wheels, but the general Spec car is growing on me, it has some nice fluid lines. Sure I don’t like the halo, but if it saves a couple of lives, I’ll make that concession (who cares...).
The current Indycars are a mixed bag, some sleek lines, but the wheel fairings IMO spoil the final cosmetic appeal. They are ass heavy.
It is not like all previous F1 generations looked great, some of the seventies cars IMO are absolutely horrific and the eighties wasn't all super models either.
...of course most are focused on the safety side of racing, sure I’d like to more competitive close racing. All imo.
