I wish designers of vehicles - particularly cars, trains and busses, would work to minimize jerk, snap and crackle.
Turns out if you minimize those, you get a far more comfortable ride. It matters far more than acceleration.
Finite element models of the whole system (tyres and suspension components and flexing elements of the vehicle body and road/track) can quickly allow analysis of the jerk, snap and crackle, and allow tuning of damping and drive system control loops to make a far more comfortable ride.
