1. While hot pink is eye catching often the blue and black ones are sold before I get to DG. Some professionals using hand held mirror.
2. Situational awareness is the hallmarks of Full Self Driving and how why FSD can become safer than humans day in an day out. Some drivers age 50+ regularly have mini strokes and never know it. Backup Cameras are not like full self-driving that's just a data gathering device.
3 Full self-driving is the computer taking hundreds and hundreds of data inputs and making the driving decision and because it has 360 vision and you and I do not have. That gives the full self-driving a leg up and just many things like it because it is fully aware or what is going on. It knows if there's potential ice on the road or not and these kind of things.
Making FSD work is very hard and that's why Tesla has been working on it so long and I would guess they're 95% there and already charge $15,000 for the software package. The hardware package comes on every Tesla that rolls out the door.
With Tesla one can lease the software for I believe like $200 a month when you need it or want it or full-time. Take for example when I'm going to be on the road for a week and driving 3,000 mi and making multiple stops that would be expensive to get hotels food I need to go along with me so self-driving software becomes almost free if you use it enough.
