One can only hope, the car and truck where in the original game with there own handling and animations, this game
doesn't feature a car model what so ever from what im aware of so we can only hope!!
Only working way plausible for now is replacing a horse carriage and using that
for it's handling physics but we'd need someone to do a conversion to replace the carriage
model with a delorean or deluxo from gta v it'd make cool sense and it'd be sweet to see the
horse pulling it and for the user to drive it manually without a horse.
