As someone who grew up in Oxfordshire in the 70s 80s and 90s, cars were not then (and are not now) the easiest way to get into Oxford. Congestion was terrible and we took the bus or used one of the cheap and convenient park and ride schemes.

That’s not so much a “law” as an absence of law, from a bygone colonial era. These days international law is based on an underlying respect for sovereignty, and alliances between states for, among other things, mutual defence against aggressors.
Minor bugbear of mine when people call House of Lords “undemocratic” for holding up Commons legislation. It is the will of the Commons, as expressed in the Parliament Acts, that HoL has power to revise and delay but not prevent HoC legislation. That they use this power is part of our democracy.
