@LukeAlmighty Oh yeah, the other reason why Paradise with the bike update aside from ESRB rating shenanigans probably lacked some of those mechanics could probably have to do with the fact that the bikes were basically "added" into the base game as a free DLC pack.
The base game never had any ragdoll animations because when cars crash in burnout and similar games like Criterion's post-Burnout NFS titles, no humans are ever depicted. There's a brutal car crash or giant deliberate pile-up like in the movies, but you never see anyone in there and absolutely zero mention is made. You just assume they're there and they exist.
Flatout on the other hand (which I haven't played) distinguished itself by having ragdolls as a gimmick and in Germany this was censored with dummies replacing humans. It's also T rated, unlike Burnout, and I'm sure that the NFS games are limited by the fact that car makers had to be convinced hard enough to let their cars be damaged in racing games (NFS MW 2013 is basically burnout with BMWs and Fords instead of fictional cars).
