Quick question: Are you saying the approaching car is doing 250km/hr (approx. 155 mi/hr)? I ask because in order for your numbers to add up, either the approaching car would have to be going considerably faster or the Tesla is not moving. If the Tesla is doing, lets say 100km/hr, then the approaching car is actually coming up on the Tesla at 150 km/hr.Well. Three seconds at 250 km/h (which isn't that uncommon,) is 208 meters. You can do a lot of braking in three seconds. Add two seconds of reaction and you land at 347 meters (yes, i know the distance would be less since the speed decreases) but with some safety margin i'd say at LEAST 350 meters, preferably 500.
