I posted this in a Tesla forum, a collection of my thoughts on autopilot. I thought others here might be interested. It was in response to some blami ng driver inattentiveness alone for a fatal accident when the car plowed in to a crash attenuator while on autopilot.
-------- I've driven my Tesla a number of highway miles on autopilot and I have a fe w things to say. When I am trying to exert enough pressure on the steering wheel to prevent the alerts but little enough to not take control back, I have to spend some portion of my focus on that task, periodically checking to see if I am pushing hard enough on the steering wheel. Most of my audib le alerts happen when I am distracted from that task by safety related even ts on the road in front of me. The mere fact that I receive an audible ale rt when I am trying to focus on the road is itself a distraction from drivi ng.
Then there is the issue of having to not only be wary of events happening o n the road due to other cars, but now I have to be constantly vigilant agai nst the car deciding it wants to do something dangerous. This is not a pro blem to wave off with a shrug.
A Tesla on autopilot is not a normal car. It is a car that lulls you into a false sense of security only to demand your full attention with a moments warning.
I've also noticed an issue I attribute to muscle memory. When I drive, my hands have a feel for driving the car. When I need to turn into a curve th e movement has little to do with my brain and a lot to do with muscle memor y. This is different depending on whether you are actually steering the ca r or you are trying to exert some amount of pressure on the wheel while jus t following the car controlling the wheel. When my eyes are on the road an d my brain is actively monitoring the situation in front of me, it is *not* always monitoring the handling of the steering wheel. So there have been times when I think I am driving and I start steering around the curve only to get the beeps that the car has given me control back. Likewise there ar e times when I think the car is driving and it is thinking I am driving. T his results in my drifting further across my lane but never my drifting out of my lane. Either way it surprises me but I can't say it is distracting enough to be dangerous. It is creepy though.
I guess the point I'm getting to is that I don't think registering pressure by the driver on the steering wheel is a useful way to determine if hands are on the wheel or if the driver is being attentive. In other words, this is very inaccurate. Assuming any given accident happens because the car r ecord shows the driver does not have hands on the wheel is a fallacy. The car has no way of knowing if the driver's hands are on the wheel or if the driver is being attentive.
If the car is good at determining when the driver is being attentive, why i s this only active when the car is on autopilot? Wouldn't it be a good ide a to have this active at *all* times? When is it good to have an inattenti ve driver????
