Agreed. Even a cheapish bike is a miracle of modern engineering, and a great force multiplier even for poor folks or folks too young to drive. I love my bike (a 20 year old Giant mountain bike that I bought to ride to college and have put thousands of miles on since).
I recently had to buy a new bike and for the first time sprung for a new one instead used, and was impressed by the equipment even on the entry-level bike I got. I'm used to bike lamps with those side clip-on dynamos, but these days even the cheapest bikes they sold had automatic light sensing bright LED lamps with hub dynamos where you couldn't even tell the extra resistance. Just feels like magic.
Yep, whenever my car needs something repaired I am going to need to pay for someone else to do it.
With my bikes I have fixed almost every by myself (except for servicing the forks on my decent mountain bike).
Don't get me started...there's always someone (many someones, usually) arguing that cities shouldn't spend money on more bike lanes, when the auto traffic is so bad and there should be more car lanes. The cost of bike lanes is a rounding error compared to auto lanes; literally, foregoing adding a couple miles of additional highway lanes would pay for a whole small city to get bike lanes crisscrossing it, and could support more people.
And, I definitely attribute my good health (well into middle age) at least partially to biking so much throughout my life. Getting a few percent more people out of cars and onto bikes would help save the world in all sorts of ways, IMHO.
