Ancient diesels or newer “deleted” diesels - all floored for maximum exhaust it seems. Also just other big vehicles. Garbage trucks, delivery trucks, etc.
But even the fumes from my hybrid are a noticeable bummer if I’m out of the vehicle.
I can tell you didn't grow up during the 70's, with leaded gas and carburetors that dumped raw fuel out the tailpipe. In comparison, today's cars emit practically nothing but water. (there's room for improvement of course - but I see that as being an EV once they get to a half-day's driving range)
