Speed and velocity explanations in principia

Here a fan powered car of 3v reach upto the speed of fully thruster rocket. You have to wait 50.333 seconds to see this truth. So levels like " fastest car" have no value. But levels named " fastest accelerating car" have more value.
Otherwise I can claim that this is [b:164ga3gb] fastest [/b:164ga3gb] car in principia because it can travel with velocity of rocket.
