The electric-car age, combined with environmental concerns, is ultimately going to limit car enthusiasts. My solution: cycling. It feels 1000x more fun than cars. I used to dig cars, and race them too. I'm now like the parent and no longer have a car because I use my bicycle (now I feel like a tourist of the unlucky people when I drive). Cycling is so much fun because it demands everything out of you: going fast requires intelligence (or an intelligent coach), incredible will power, fitness (which you build), and situational awareness. Instead of caring about the mechanics of an engine and the car, I care now about my physiology (which is amazing), and learn how to understand the uncountable ways we fatigue. My retirement will find me with muscles like those of a 40-year old. Bike racing is very intellectually taxing, and it is a shame that it is under appreciated in the U.S.
