1 - Today i parked it on front of my garage after a 25 mile drive, went in house for a few minutes, came out, put it in Drive and the headlights came on and all the sounds were normal but the screen was totally black. I put it in park again, then drive, same thing. I'm thinking WTF. I drove slowly around my neighborhood and about 3 minutes later a Tesla "T" symbol showed and then the screen was there. LTE was not available for a few more minutes. I'ts almost like it went through a boot sequence? 2 - I noticed weird shaking in my steering wheel. i thought it was a problem but i think it may be a feature as it happens when I go near a solid line on the side of the road. feature? 3 - I was thinking when i use regenerative braking are drivers behind me seeing brake lights or do they come on as a safety precaution. i can't see as i'm driving so...do the break lights come on when you are using regenerative breaking? Thanks!
