Changing direction by definition is an acceleration. If it wasn't, then all our math about planets, rockets getting to planets, etc, would be wrong.

A steering wheel could be called a "centripetal accelerator", since it induces acceleration toward the center of a radius/circle.

This is high school level physics, one of the first things you learn.

Face it, planets are hanging from the celestial ceiling - on wires. Galilei's herecy has been debunked. The end is nigh! Eat more sawdust! Ahoohaa!

Yeah I think the guy above you has an argument though. The steering wheel only acts as an accelerator if the vehicle is actually in motion. But then the brake also does that, so maybe there is a point in naming them differently.
