Britain is in crisis with cities losing billions in productivity from time lost in traffic jams.
One of the journeys I do from time to time takes about 10-15 minutes by car . Just once I went by bus, I forget why, it took well over an hour door to door. That's a fair trade if your time's worth 5p an hour and a bus happens to be going from your A to your B or nearby. But it's just not workable fo r most journeys for most of us. Abandoning private cars is not in any way a workable way forward.
Expanding the road network greatly in towns & cities is not in any way a wo rkable way forward. Expanding public transport greatly in towns & cities is not really a workab le way forward, the vast costs of London underground type networks all roun d the country are not really affordable. We're stuck between a rock, a hard place and a sheer cliff.
What options remain? Congestion charges don't solve much, they're merely a way to scam a load mo re money off people that have to go to & from work, buy food etc. Networks of zip lines could move parcels, but only between a limited number of nodes, so could only remove a small percentage of road traffic. Transitioning from car to motorbike is too dangerous for most people to con template. A new 2nd layer of overhead roads is just too expensive, and in most places unworkable. Stacking occupied cars multilayered onto trucks takes too long to load & un load to help to a significant extent, plus would cost, and you can't go abo ve 2 layers anyway due to bridges. More competent traffic management is needed and would help, but isn't going to solve the problem on its own.
That all leaves just 1 option as far as I can see: separate lanes for micro cars, which are barriered off from larger vehicles. 6-8 microcars can sit i n the space of 1 standard car (when still or very slow). They're far cheape r to make & much cheaper to run, and they can be far more fuel efficient, w inning green votes. They won't do everything but are sufficient for a sizea ble percentage of town & city journeys. They would only be permitted to do
20 or 30mph max. FWIW I'd get one if they could be used.NT
