Those who said "oh the guy behind should've left enough room for the Tesla to merge" just don't understand the situation.
You mean to tell me, that you're going around 50/60 (whatever the speed limit is on the highway), someone ahead of you wants to merge into your lane so you let them and give enough space...and if that car suddenly stops dead in their tracks that you'd have the wherewithall to stop before you come into contact? Nobody expects a car to stop dead in their tracks on the highway of all places, even if the car was like, 5 car lengths ahead.
Nobody's a perfect driver with split-second reflexes and a car with damn good brakes that can stop on a dime. Quit acting like one. I'm a safe driver and I almost assuredly would hit the person in front of me if that happened to me.
