    It’s geometric, not exponential. Going from 25 to 28 freedom units is factor 1.12 and v² increases by factor 1.2544 or 25%.

      But at 60mph if you crashed into a wall you’d vaporize instantly. Because exponential.

        No exponential. Geometric. Squared. Energy is E=mv². At a speed of 60 freedom units you’re going factor 2.4 times faster than at 20. The energy will be factor 5.76 times higher. Or 476% more if you like.

        The word exponential has a specific meaning. It doesn’t just mean really big.
