'Cause it's the cyclists that need educating...

Hmm, I like the version of the poster with the cycle lane drawn in. It does rather point out the contradictory policies going on here!

There is a Low Emission Zone scheme in operation in various parts of London. This is similar to the congestion charge except that it only affects HGVs, busses, etc. which do not meet certain emissions regulations. Also, the charge is much higher - £200/day with up to £1500 penalty for non-payment. The idea is that it slowly forces businesses to update their transport fleets to more modern, greener vehicles. In turn, this also pushes manufacturers into making greener vehicles in the first place on the assumption that such regulations are only going to get stricter.

Surely it must be possible to do something similar for blind spot problems? Any vehicle that does not have blind spot mirrors gets charged. Maybe a sliding scale to ease introduction - £5/day this year, £50/day next year, £500/day the year after. Then do the same for proximity sensors, driver training, etc. There definitely needs to be something to force such upgrades and to push manufacturers into designing better visibility from the outset.

Commercial fleets aren't effected at all by the low emmissions zone is just idiots like me that have older vans and trucks and busses.
