Stop the car or wait.
I know that both suggestions are absolutely outrageous in a culture where the majority of people seem to have developed a "must answer the phone when it rings regardless of circumstances" behaviour but it's a question of retraining unthoughtful or bad habits.
Hopefully it won't be too long before phones won't work in moving cars and all cars are automatically restricted to the speed limit.
