How does a system that works in 95% of situations require “no supervision”. What happens in the 5% of situations where it fails to work?
If it fails to work while in the middle of driving, and it is not under supervision….that sounds like it leads to a somewhat suboptimal outcome. Perhaps I’m misunderstanding the definition?
What percent of the year is it snowing, icy, slushy. That alone is more than 5% for some people.
What happens then is the system states it is unable to engage, you have to drive yourself buddy.
What percentage of the year is it raining at cyclone, hurricane, hailstorm, your wipers can't keep up level of rain? Again for some places that is more than 5% of the year.
Again if the system can't drive in those conditions you park and wait it out or you drive at your own risk without FSD.
What percentage of the year are there flooded roads or standing water that the depth can't be gauged.
Again if the system can't drive in those conditions it'll let you know and it'll avoid them. You can turn around or risk your life.
I'd happily pay big bucks for a FSD system that could only handle 75% of the situations I drive in on a yearly basis. If it refuses to drive any time the ground temp is below 32F I can live with that. If it refuses to drive when it's raining cats and dogs I can live with that. The vast majority of my driving is on dry pavement and if it can handle 99.9% of the dry pavement driving and even half of the wet pavement driving I do* I'd put up with 0% capability for some pretty large categories of weather.
* I live on the edge of a rain forest in the Southern US, we get storms here that can be strong enough I won't drive in them. We get flash flooding that make not just parts of roads impassible, entire neighborhoods or maybe even the whole town could be immobilized. But stuff like that is an exception, it doesn't happen every year, let alone every season, month, week, or day.
Do you really expect FSD cars to handle road conditions I won't deal with myself?
