Sounds like this guy is incompetent as a driver, independent of his skill as a car reviewer.<p>Your car breaks down in the highway in California? Call CHP (911 should go there)?<p>Leaving your car visible only from 4-way hazards is...questionable. Flares and/or LED flares and/or marker triangle placed behind the vehicle would allow drivers to notice your disabled vehicle before being a threat. Emplacing flares can be dangerous, though, if traffic isn't already stopped. CHP will do this for you, and is the safest/default option. In civilized parts of the country, commercial truckers or good samaritans may stop to help you if you pull over and have your hood open (I'd personally definitely stop for a Tesla driver, even in LA, just to see what the problem was, and my trunk has emergency stuff like flares, hi-viz jacket, etc..)<p>Getting out of your disabled car stopped in the roadway or on the shoulder is often unsafe, too, although it depends on where exactly this was; if you could walk off the roadway entirely, sure. Otherwise, getting rear-ended while sitting in a car is far better than being run over outside it.
