Yes, and when the poles are down the ends extend no more than a foot beyond the rear bumper. Poles sized for an automobile would extend several yards past the rear bumper when tied down, which is never going to pass muster with the DOT.
so one idea i for every bus stop along a trolleybus route to include either an overtaking loop in the wires and/or a re-wiring trough, this wolud make it easier for trolleybuses to leapfrog, and would be important if trolleytrucks went along these routes.
Never going to happen. TTs have to go slow through special work to avoid dewiring, so adding passing loops at every stop (remember, many stops are only a block or two apart) would have a net effect of slowing down the entire route. On top of that, the frogs would either be set based on current draw in the section immediately before the loop (in which case everyone using the wires has to know the trick for throwing them in the proper direction), or they would be normally set to one route and someone wanting the other route would have to stop and get out to push a button on the nearest pole.
Have you actually put any thought into the actual utility of adding trolley poles to trucks or automobiles? As someone already mentioned, there's only a handful of cities in North America that have TTs, each with only a handful of routes. Given that a truck or car is typically only going to spend a short (if not completely insignificant) part of a trip running on the same road as a TT, the minuscule environmental benefits of running as an electric vehicle for those few blocks are outweighed by the cost of installing trolley poles on said vehicle and the longer time needed to traverse that segment of the vehicle's route.
Also, where is Silver Way?
