Immobilizers (which lock out the engine until there's been some authorization from another device, i.e. from a chip in the key) have been mandatory in cars in the UK at least (and I would presume Europe on similar time scales) for almost 30 years (from 1998). Seems they've been sold in cars for a few years longer than that (from 1992). According to: https://www.carwow.co.uk/guides/glossary/what-is-a-car-immob....

Maybe never introduced into the US market? Would find that hard to believe.
