In static friction, the frictional force is whatever value it needs to be to prevent sliding up to some maximum value. Technically, this is called Amontons' First and Second Law of Friction.
Method 1: Using distance. Suppose the cars are traveling at 84 meters per second (I roughly measured this from the video), and then one starts to slow down because of the frictional force.
Travelling between stops, the average frictional force on a bus was \(8\cdot2\times10^{3}N\) over a distance of 500\(m\). Calculate the work done by the bus engine to overcome this frictional force.

Given that assumption, the result is that, yes there is a frictional force, and his description of it agrees with other, non-quantum descriptions. Pendry must be right, because of quantum mechanics.
