Will it be correct to say that the car moving in a circular path with constant speed has uniform acceleration?

Well, it depends on the environment, but say we are in the most perfect environment, flat, constant friction, no air resistance, no resistance on the car's internal workings, then yes, but say it was going 30 Km/h, then it would keep accelerating until it reached 30, then it would just keep moving at 30 Km/h
