And 1" or so of bike tire rubber isn't as good an insulator as a car tire. Second, that lightning current will be dispersed through the car; in the car you'll probably say "Wow!" and, at worse, need to have some wiring and electronics replaced. That's harder for a neurologist than for an auto mechanic.
I ride one of them plastic bikes, so I have a little more insulation from the ground than just the tire. Come to think about it, the only ferrous metal parts on my bike are probably bolts. In reality, I'm not going to ride in a thunderstorm because I'm soft AF with weather.
EDIT: I guess I can add spokes, bearings, and BB spindle to the ferrous metal parts. It still ain't a whole lot.
