No one does FSD yet - properly.

It initially seems mad that a human, inside the box can outperform the "finest" efforts of a multi zillion dollar company. The human has all their sensors inside the box and most of them stymied by the non transparent parts. Bad weather makes it worse.

However, look at the sensors and compute being deployed on cars. Its all minimums and cost focused - basically MVP, with deaths as a costed variable in an equation.

A car could have cameras with views everywhere for optical, LIDAR, RADAR, even a form of SONAR if it can be useful, microwave and way more. Accellerometers and all sorts too, all feeding into a model.

As a driver, I've come up with strategies such as "look left, listen right". I'm British so drive on the left and sit on the right side of my car. When turning right and I have the window wound down, I can watch the left for a gap and listen for cars to the right. I use it as a negative and never a positive - so if I see a gap on the left and I hear a car to my right, I stay put. If I see a gap to the left but hear no sound on my right, I turn my head to confirm that there is a space and do a final quick go/no go (which involves another check left and right). This strategy saves quite a lot of head swings and if done properly is safe.

I now drive an EV: One year so far - a Seic MG4, with cameras on all four sides, that I can't record from but can use. It has lane assist (so lateral control, which craps out on many A road sections but is fine on motorway class roads) and cruise control that will keep a safe distance from other vehicles (that works well on most roads and very well on motorways, there are restrictions).

Recently I was driving and a really heavy rain shower hit as I was overtaking a lorry. I immediately dived back into lane one, behind the lorry and put cruise on. I could just see the edge white line, so I dealt with left/right and the car sorted out forward/backward. I can easily deal with both but its quite nice to be able carefully abrogate responsibilities.
