EV3 Car

Hi everyone. I like to build cars out of LEGO. I tried to make a car with the Mindstorms parts but I’m missing a Programm. I tried programming and in theory it should work. I tried it and it was kinda buggy (for example: it wouldn’t register the press on the remote) (picture of code below). Online I read about ev3dev, maybe I could have more efficient code -this scratch style code kinda frustrates me. On the internet I can’t find projects of cars with Mindstorms hardware. My car: 2 L- motors...
