If it is a recent model car, with clear coat (1990s and newer), Acetone is safe for removing tar/asphalt splashes. Acetone can affect the finish if allowed to soak for a long period of time, however, it evaporates very quickly so this is not usually an issue. Fingernail Polish remover is very often Acetone with scent, as well as many "tar removal" products from an auto parts store. If you wax your car, you'll need to re-apply the wax after washing.
If your car does not have clear coat, the finish tends to turn white/chalky after sitting in sunlight, if the car is washed and waxed, acetone will remove the wax, so re-applying wax is more important than vehicles with a base/clear coat finish.
