I was driving today and stopped at a stop sign waiting for a garbage truck to pass, but then it turned on its blinker and turned right. I noticed that both the passenger AND driver side had steering wheels and both were turning their steering wheels. How does that work???
In: Engineering
In Germany, driving schools have cars where the instructor has their own set of pedals and the two sets are mechanically linked. Even [a second steering wheel](https://www.abendblatt.de/region/kreis-lauenburg/geesthacht/article232575611/Ein-eigenes-Lenkrad-fuer-den-Beifahrer.html) can exist, although that’s not typical. I don’t know about your garbage truck, but I guess it’s similar for its steering wheel. Linking two wheels to move in the same way is pretty easy to do.
