The author (who I believe is in the UK) did not address 2 related industries/issues that are likely to be impacted more here in the US:
Insurance--collision, property damage, and, most important, personal injury/liability. If autonomous vehicles meaningfully reduce collisions, property damage and injuries/deaths, there will be a radical shift in the insurance industry.
Legal--in the US, there is an enormous industry based around motor vehicles, specifically collisions, personal injury and death. With fewer collisions and injuries, there should be a substantial reduction in litigation. Lots of underemployed lawyers, and maybe some reduction in the burden on overcrowded courts. FWIW, I was just in south Florida, and every other billboard seems to be advertising a law firm offering their services to get you (...and their firm) money for your injury/accident.
