What was the gas/brake configuration like in a 1922 Nash Roadster? It doesn't specifically have to be the 1922 model--hell, it doesn't specifically have to be a Nash--since the story is set in an alternate universe US circa 1926-1928, so I have room to play a little fast and loose with actual facts. But a fairly cheap and sporty car of that era, would it have the brake pedal on the floor yet? Because I'm almost sure the earliest mass-produced, priced-for-the-middle class cars had a different mechanism than what the ones now have. I'm almost remembering it being a handbrake, but I could very easily be completely imagining that.
I feel like I should know this since I did my undergrad history major mostly concentrating on the US from about 1900-1940 and I can almost remember reading about that. But I've looked on Wikipedia and some vintage care restoration sites and the Google, and in some classic car books at the library where I work. I just cannot find any good pictures of the driver's side interior of a car from the era I'm looking for or much about what the various bits of it do.
