I'm not sure that speed matter for a lot of freight. Fresh food, perhaps. But a lot of stuff is shipped around the world on shipping containers that take weeks to get to their destination, and no-one particularly seems to care.
At least, so far.
What makes buses and trains so attractive is that they take up far less space (if filled) compared with say a car carrying one passenger.
It might be too late in the UK to get cargo and freight back on the canals. Also our local post offices are being closed down, which would be the natural choice for a local pickup point. I for one wouldn't mind a text to say I have a parcel to go and collect. I'd probably be happy collecting my mail once a week (bar the spam.)
Side tracking further, I heard some old dears the other day, lamenting that they could no longer afford to send xmas cards. It now costs about a dollar to send mail by first class.
