Many/most minvan drivers avoid having to "brake hard". They do this by anticipating braking ahead, and, frankly by driving slow and generally "smooth". Drive like the president is in your car. After all your kids may be president someday. Many of these insurance companies which have the device to check your driving for a discount, suggest not doing "hard braking" whenever possible. No jack rabbit starts and stops. Of course, even with great driving emergency braking has to be done. Sienna drivers are looking for fuel economy, and drive conservatively. I love the regen braking but do get there is a tradeoff for stopping distance.
