i find it interesting there is little to no concern or thought to lives that can clearly be saved by investing in the appropriate infrastructure. Any talk of the consequences of poor design, deaths aka body count, is wiped away as hyperbolic.
If loss of human life doesn't spur some to action or convey the severity, what will? What we should probably do is tell us americans we are taking away their bikes, then maybe we will get all kinds of support? Maybe we should say main stream media wants to take away all our bikes?
Infrastructure is a battle cycling advocates have been fighting since before ebikes even existed as a thought in someones head. Discussing ebike-specific stuff doesn't mean people don't care about general advocacy, its just a big issue to tackle. Living in NoVA I've seen bike infrastructure gain a lot of ground since I started bike commuting in ~2005, but it still has a ways to go. As rawlus noted above, its a very local issue. You fight and win small battles, and then build on that to grow ridership and take on bigger battles.
Anyone who cares about it and wants to contribute needs to find their local group and get involved.
