> was the apparent benefit so incredibly variable?

Yes, lots of people were very vocally against horseless-carriages, as they were called at the time. Safety and public nuisance concerns were widespread, the cars were very noisy, fast, smoky and unreliable. Old newspapers are filled with opinions about this, from people being afraid of horseless-carriages spooking other's horses and so on. The UK restricted the adoption of cars at one point, and some Canton in Switzerland even banned cars for a couple of decades.

Horseless-carriages was commonly ridiculed for being just for "reckless rich hobbyists" and similar.

I think the major difference is that cars produced immediate, visible externalities, so it was easy for opposition to focus on public safety in public spaces. In contrast, AI has less physically visible externalities, although they are as important, or maybe even more important, than the ones cars introduced.
