All it takes is a couple opsec slip-ups to give a dedicated group of attackers the clue they need to link your identities together. Maybe you'll never make a mistake or say something that the wrong kind of person takes umbrage with, but is it really fair to put that task on every single Internet user?
Any cars that have "automatic lane holding" could definitely be told to swerve left. Granted, steer-by-wire systems like that aren't quite pervasive yet. I believe electronically controlled throttle or brakes are more common. Locking individual brakes especially could quickly lead to a very bad situation. Also, putting the car in neutral or removing the key is likely not something that is going to occur to most people in the 1st half second or so that all this is happening.
I think one of the key differences this time is the amount of retraining involved. Taking a farm worker and teaching them how to work on an assembly line involved orders of magnitude less retraining then training an assembly line worker to be a teacher, psychologist or nurse.
The key part phrase there is "[c]ompared to the ThinkPad of the day". IMHO, MacBooks and ThinkPads were nowhere near comparable in build quality until the the MacBooks went to unibody aluminum construction.
It still kills me to see everyone using 192.168.1.0/24. IMHO, there is only one reason not to use 10.0.0.0/8 and it's because that can sometimes conflict with the address space commonly used for work VPNs. If that's an issue, an arbitrary /16 from the 172.16 - 172.32 range would be a good bet. I haven't really been using cheap consumer routers with their stock OS in a while (maybe 10 years), but is it still common for them to be stuck on 192.168.x.0/24 for the LAN side? I kinda assumed this was more of a problem from like 10 years ago, but I could be wrong I guess.
My $20 totally off-brand bluetooth headphones support multi-pairing. Does it always work 100%? No. Do I think cheap multi-pairing capable headphones will get a lot better as it becomes more important? Definitely.
