@urlyman@mastodon.social Nice hashtag! When it comes to efficiency of energy and use of space the bicycle wins hands down over cars. I've not seen the 1/20th stat on road wear though. The only thing I've seen previously about road wear is the "Fourth Power Law". If it holds for bicycles, a 1000kg car causes 10000 than an 100kg bike and rider (if my math is right) https://en.wikipedia.org/wiki/Fourth_power_law
