OK so people warm up to feeling safe that their cars are talking to each other and can therefore spend more time worrying about who just BBM'd or emailed them, the car will worry about the rest. Then the guy driving along in his 1985 Ford F350 blows a stop sign and everybody sues each other because the car was supposed to keep everybody safe from everything.
I'm all for better safety, but I think that it should come from better drivers not a raft of (expensive) passive safety measures.
