With the news about Uber and Tesla accidents, it’s been making me wonder: why not equip these cars with one more sensor: an infrared camera. Combining thermal information with extant information will be a great boon in making intelligent decisions, no?
I 100% agree but I would bet the issue is unit cost for the hardware. Anything with reasonable resolution is going to be in the four digit dollar range per sensor.

Beginning of pranks to come with self drive cars. Imagine when someone realised you can slam on the brakes in front of X brand of car and it prioritises avoiding the car in front over all else
Hopefully the expensive self driving car can afford to integrate a $40 dashcam.

If there are 2 seconds of distance between cars at 36mph and 2 seconds of distance between cars at 18mph then the road has exactly the same capacity at both speeds. Also, the constraint on street capacity is intersections in the vast majority of cases. Until you remove intersections nothing else really else matters.
You're also underselling the intersections part, because getting traffic to intermix at intersections is incredibly easy at 20mph. And, what you've conceptually stated (no loss in capacity) has been empirically demonstrated. Finally, you get vastly different places at 40 mph vs 20mph. At 20, roads are smaller, people can safely exist close to the roadway and even enjoy themselves, and you don't need huge buffer zones…
