I wasn't too sure whether to mod you up (anyone advocating safe driving certainly should be heard) or reply with a disagreement..
1) Perhaps the bycyclists should start footing that bill?
How about bike registration and insurance if you have >13" wheels and ride on any public bike lane. The insurance would be some $20/year anyways, it's not like there's much potential public liability.
2) while I advocate better and safer driving, if a road is 45 around a bend, I go 45 (I interpret 45 around a corner as being a bend in the road, not a literal street on to avenue corner). No slower, no faster, everyone going the same speed is the safest possible condition, whatever that speed may be.
