Improved software, and maybe one hardware refresh should be sufficient to get us all the way there for 99.99% of drives.
Aside: some really old drive assist tech for snow plows on I-80 Donner pass - https://path.berkeley.edu/sites/default/files/advanced_snowp... /// https://highways.dot.gov/public-roads/janfeb-2001/safe-plowi...
I'm still waiting to see how an AI would handle Figure 5-1 from that. And no, the snow plow's solution of burying magnets in the road isn't practical (Cost of infrastructure installation for the test sites is approximately $11,000 per kilometer ($17,000 per mile), including surveying, installation, and magnets).
99.99% means 1 in 10,000 "drives" has an accident of some sort? So 100 accidents per million people/drives?
Not sure how to compare if that is better or worse than what we have now.
