I drove my dad's Tesla 3 all weekend. Cherry Hill --> Atlantic City --> Union --> New Brunswick and back.
Used Autopilot extensively.
For me, it's just -- OK.
There are still too many situations where it makes a "WTH" maneuver and you have to override it.
3 examples:
- Traffic cones - Route 70 in South Jersey has a lot of construction going on. The cones register fairly accurately on the screen so I know the sensors are picking them up. However, it has a difficult time processing the lane markers on the road vs where the traffic cones are actually trying to get you to go.
- Speedy drivers - When I'm on the highway and driving normally, I'm constantly scanning my rearview. When I was on the turnpike, the Autopilot was going to change lanes right into the path of a car that was barreling down the left lane. Had to override.
- Merging - Turnpike again. When merging onto a highway, the Autopilot's logic tends to hug the white line on the right. So you end up merging at the last second possible. Meanwhile, there are people behind me who were already merging and accelerating into my projected merge path. Was very uncomfortable and never trusted it in that situation again.
When it's fairly open highway or bumper to bumper traffic, it's a pretty neat feature. Quite useable for those particular use cases actually.
Still, it's not quite "there" yet and I'm not sure it ever will be unless also combined with smart lanes (ie: superhighway with dedicated self-driving lane where cars & road can all communicate together).
Definitely not ready to trust it in a more urban setting with bikers, pedestrians, pets, kids, etc.
But -- I think the technology is amazing for supplementing a driver. You sort of feel like Iron Man because there are no blind spots and sensors can see better than we can in the dark or rain.
