My father sits through 2-4 hours of Los Angeles rush hour each day, and this is absolutely a game changer for someone like him. This is stellar.
I expect a slow phase change to car-as-public-transport that never stops rolling when it isn't in maintenance.
Now, suppose your self driving car let's you work while in the car. So, your still in the office from ~10-4 and get daily face time, but your only working 8-6. From a work life balance that's effectively zero commute time vs a killer 2h each way, with the added benefit that you get to avoid some of the peak traffic times.
The upside is it makes vary long commutes viable, the downside is it's it's vary energy expensive but with electric cars that's far less of an issue.
No to mention things like effective valet parking everywhere.
It's incredible how less mentally wore down I feel after a long commute when using TACC. Still paying attention but at lot less effort required.
What Tesla is releasing at this stage brings absolutely nothing new to the table.
My Landrover has this technology as an option as do most brands e.g. BMW, Mercedes.
Tesla is merely playing catch up this in regard.
