Tesla's PR handling of it hasn't really turned me off the idea, nor has the car's action of veering off the correct course (because that's occasionally expected), but the collision itself is disconcerting to me. I would have expected the technology to be sufficient to brake to avoid/reduce the severity of the collision. The horror stories about defects and lengthy repair times haven't exactly helped. It's a bit of a moot issue for me though, as I probably won't be in the market for a new car for the next two or three years.
