Thanks for that update.
4.2% of vehicles does not of course equal 4.2% of vehicle miles, but might be broadly similar.
4.2% is more than I expected, but still not "significant" by my arbitrary definition of at least 10%. Still better than nothing though. Hopefully we will see more in the future, and possibly a return to trolleybuses also.
Has risen to 7.4% in the latest figures covering up to March.
Glad to hear that, it is now approaching my admittedly arbitrary definition of "significant" as being 10% or more.
For longer routes, I would hope to see trolley wires installed in order that the vehicles may charge in use.
There is nothing that hard or expensive in installing trolley wires on straight or gently curving roads. It is tight curves, crossroads, roundabouts, and railway crossings that are more challenging. The same infrastructure could power electric delivery trucks.
