Problematic questions would be raised about cars that redlined certain city neighborhoods.<p>There is illegal robbery and legal robbery... once neighborhood redlining became popular, you can guarantee cities would start raising revenue by ticketing self driving cars caught cruising residential zones, entertainment districts, etc.  We have plenty of existing laws and case law against &quot;cruising&quot;.  You can imagine the bug reports already &quot;Your service failed to inform my car that the sportsball team was having a game last night, placing the stadium district under no-cruise law, so I got ticketed, towed, impounded, and had to pay for a taxi home&quot;
