If it’s a push button ignition you have to, so almost all new vehicles. On keyed automatics, no. There are VERY few cars on the road that would start in drive or reverse or low. This is an old warning. Manuals on the other hand, again, almost all have a clutch interlock to start, but a lot of trucks and jeeps can have clutch defeats and will move when the starter is hit while parked in gear. It’s pretty dumb, but there are tiny scenarios off road you might want that. Most people just don’t want to press the clutch to start for some reason. In many of these vehicles it’s as simple as pulling a fuse.
