@rrspur @Lucyincanada Well, yes and no.
I've been in a 1947 3 ton with a 16 foot bed from back in the times you are talking about. It still took 3 lanes to get around a corner. It also wandered a fair bit, so you needed the whole lane (no power steering) and was just as wide (102 inch deck) as a modern truck. The mirrors and overall visibility sucked. You had to be a witch to shift gears. It was harder to drive than a modern semi. I liked it a lot.

There was a lot less traffic back then though, and more people understood how large vehicles moved.
Also, the guy driving it hadn't just pulled into a strange town, not knowing where he was going or how the city worked.
I agree we need to get back to rail more, but I don't see that addressing the trucks on the city roads issues very much because there's still that final mile problem.
