Does a car driving around a curve at a constant speed on a flat road have a constant velocity?

NO. Velocity is a vector quantity dependent on both speed and direction. Driving around a curve is a change in direction so velocity will not be constant. If you drive rapidly around a curve you can sense the acceleration which changes the velocity. You will experience a force which tends to try to move things away from the curve. On a bicycle or better, motorcycle, this has to be countered by "leaning into" the curve so that your weight is displaced from being over the wheels to being over the space inside the curve. This allows gravity to counterbalance the force due to the acceleration.

Or...to put it more simply...No.
