Since the right foot is normally used (for the accelerator or brake) there is no foot rest on the right, not even in cars with cruise control. The left foot only has to operate the clutch intermittently (or has no function in an automatic vehicle) so sometimes a foot rest is provided to the left of the pedals.
Many cars now include pedals with electric adjustment, a modern iteration of a manual adjustment system available sporadically since the 1950s.
