Humans are no different in that regard – our roads are too congested and over capacitated. I had never heard of the term road-rage when I started out as a road-user in the mid 70s, but now I witness it on a daily basis.

IMHO we will reach such a level of saturation on our roads that we will be faced with two choices. Either do nothing allowing the status quo of a gridlocked roads network to remain, or encourage more public transport use by making it a more affordable alternative.
"To small a confined space"? Like this thread? Lol
