Android / IOS: long tap on the machine, press the Drive button to sit in it.
Windows 10: right click on the machine to get into it. To start the engines, you just need to take the key (carrots on a stick) in your hand while sitting in the car. If you want to stop the car, then just switch to another slot in the hotbar. You can also open the inventory of the machine. Either sit in the car, or sneak up to it and hold your finger long on it to open inventory. There are 27 slots available for storing things. Arrange these races with your friends in MCPE thanks to this car!
