Lambo (all sport cars) owners tend to take speed limits as suggestions, it might actually be going twice as fast if not legally, still people being driven around, would prefer a Rolls.
Rolls and Bentley are normally driven slower than even regular cars like high end sedans, they are big and unwieldy, and their passengers really care about ride quality, the scene from parasite about coffee cup comes to mind.
If you had the money to own either car, you are rich enough that whenever you reach the destination is on time, other people work on your schedule, then speed becomes less important.
