> the risk of losing your connectivity is too great. Additionally the risk of benign or malicious interference is too great. We can't live in a world where a 14-year old with a soldering iron and $20 in parts can jam 12 lanes of traffic at rush hour. Or where a solar wind or foreign enemy can cause mass casualty events such as disconnecting all autonomous vehicles simultaneously. I wonder if a low bandwidth directional link might be best. Where all cars in a "pack" agree they have the same firmware. Then do each others calculations and then confirm whether they agree by only checking a hash of the calculation. This would be a much smaller payload and could be transmitted on redundant channels on different bands. It would at least be harder to jam.

Although they don't generally do that, protesters do pretty much the same thing (that's how we all first started hearing about BLM, recall).

Doing that puts them at severe risk of detection and capture, doesn't scale well, is pretty easy to remedy, and dealing with foreign objects on roadways is pretty easy (people drive around them, and maintenance personnel and/or police move them off the road) and needs to be because it happens all the time without any malicious actors involved.

  Punks throwing shit off the overpass definitely couldn't stop a 6 lane freeway in both directions, but yes I see your point.
