Re: What GPS really needs
Sorry, but some roads are narrow. And some people, against all common sense, choose to live on those roads. What's a delivery company to do?
Use a smaller vehicle? That would add cost, which means they'd have to jack up their prices, and would promptly go out of business because other, less-scrupulous players would use their lower costs as a competitive edge. Or they could refuse to service those addresses? - same result, with added vilification from the would-be customer thrown in.
After all, whoever's sending the package - Amazon? - whatever, they don't give a damn' about the garden wall of some unrelated codger who'll never even know who was responsible for damaging it.
Damage to third-party walls (etc.) is an externality, that the delivery company doesn't have to pay for. As long as we allow such things to exist, the incentives will remain all to cock. We need to charge people for the things they break - even if nobody sees them breaking, even if nobody even knows who owns them.
And that, in a nutshell, is the case for a carbon tax...
