Here's a quick anecdote, just slightly off topic. I was driving in the super fast lane during driving rain the other day and one lane over some siht happened, so a pickup truck pulled out right in front of me to avoid the guy in front of him and I was going way faster than that pickup. I hit the brakes, full-on panic mode. As is the case in these situations, time slows way down and I heard myself thinking repeatedly "Aw siht I'm going to hit this guy" and got closer and closer, all in a fraction of a second, still thinking "I'm going to hit this guy" and then ... no collision. My passenger had exactly the same experience.
The i-Pace has a very very short snout. If it had been longer I would have hit the guy. It's a psychological rear end collision avoider.
