This wouldn&#8217;t eliminate potentially deadly interactions between the police and the general public, but it certainly would reduce them.<\/p>\n\n\n\n<p>Maybe have a single exception: passing another car that is going more than 10 mph slower than the speed limit on a two-lane road. The Odyssey already has all of the hardware and 99 percent of the software necessary to detect this situation (the adaptive cruise control has a radar to see how fast cars in front are going and the lane-departure and lane-keeping systems (the latter adds some steering inputs) use a camera to see if you&#8217;re staying in your lane.<\/p>\n\n\n\n<p>Readers: <a href=\"https:\/\/youtu.be\/TrKqBlZdOTk\">Stupid or Clever<\/a>?<\/p>\n\n\n\n<p>Related:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/philip.greenspun.com\/blog\/2021\/02\/05\/save-lives-by-limiting-cars-to-35-mph\/\" data-type=\"post\" data-id=\"30972\">Save lives by limiting cars to 35 mph?<\/a> (if we look at what we&#8217;ve done out of coronapanic, it is irrational not to eliminate most driving-related deaths, which kill far younger people (more life-years lost) and which are far easier to prevent)<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Every time there is an interaction between an American subject and an American police officer or officers there is a chance that the police will shoot and kill [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[35],"tags":[],"class_list":["post-32211","post","type-post","status-publish","format-standard","hentry","category-cars-including-self-driving"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>To cut interactions between the police and the public, should cars restrict speed to the published speed limit?
