It would only work as long as you’re going a straight line and never need to pull over or pass.
I was a patrol boy on the corner next one of Chicago’s CTA bus turnaround that the electric buses - converted streetcars - used.
Every single time a bus left and turned the corner the trolley poles would go flapping and the driver would have to come out and go back behind the bus and put them back on the wires. When you were on the bus and it pulled over the same thing would happen. All of the lights would go out and the whirring motor noise would stop until the driver got it plugged back in again.
