Okay, but I think you missed the situation. We agree that braking is needed. But then what? We still have to choose which way to steer. Steering straight ahead could/will kill a child. Swerving...

At some point a choice must be made about what to steer towards. I don't see how it can be avoided. The car needs to decide which course of action between two or more choices where all choices will...

I agree that in many situations a driver is currently unable to make such decisions in a timely manner, but that is not the issue I raise above. The issue is about apportionment of blame. In the case...

When your car comes with no steering wheel or controls pedals at all -- i.e. it becomes a robot with its own software driving everything -- then who takes the blame for accidents and fatalities? What...

Hehe, indeed. I've seen it firsthand also. Kind of stretches the meaning of car though. I'll give half credit for the humour content.

I'll have to take your word for this as I have no experience here. But I will fallback on my previous comment about the solution being practical. The above is clearly for the petrol heads and boy...

I wasn't thinking of that. The double clutch thing doesn't count because as you apply the accelerator the effect on speed is nothing. I'm looking for a situation where applying the accelerator is the...

I would expect your wheels are already skidding (backwards) if you have released the clutch and the gear is opposite to your travelling direction so in that case applying more fuel is unlikely to...

There are some other driving "tricks" also.

Extra credit to those that can spot the following situations:

1) Applying pressure to the accelerator pedal to reduce speed.
