First Tesla Autopilot Death

[VectraMan]

Autos lock up the gearbox when you select park so that's kind of the same as the handbrake.

I don't know the 'touching the flap' reference, but I drove my Dad's Espace and had a nightmare time with the e-brake. I was trying to balance the clutch and throttle and release the brake as you would with a normal handbrake with the added complication that it was a LHD car. He told me afterwards that you just drive off and it automatically released.

You're all so prehistoric. The car will be controlled by an app, surely.

So, you're getting it on on the front and as well as trying to film it on an IPhone, you have another, in your hand, trying to control the vehicles brake?

Call me a Luddite, but I can't see that working

You think you'd have an audience for your smut video? Not exactly amputee midget p0rn is it?

OK, to partially or mostly answer my own questions above. this article appears to suggest that an flap/button (electronic) handbrake cannot be engaged while the vehicle is in motion, even if you pull the flap (or, depending on the make, press the button):

2016-01-04 What is an electronic handbrake?

So it's reassuring to know that I won't be doing any vehicular pirouettes on the motorway by accidently engaging while at high speed!

(Well, reassuring only in so far as one trusts electronics and software, unless the handbrake disk also has a mechanical governor to prevent it engaging while in motion ..)

With a few tweaks, for sure, it has potential.

Oh, posters on this PistonHead thread said that holding the flap/button for two seconds fully engages the hand brake and brings the car to a stop ASAP in the direction it was pointing when the breaking started.

Apparently the idea is for a backup breaking system if the main brakes fail, or for emergency use by a passenger if the driver is incapacitated somehow

(Two seconds sounds like an awfully long time to wait if the vehicle is at high speed, although perhaps it starts kicking in more gently earlier and builds up.)

Maybe, but what happens if they park in a 1 in 2 hill to enjoy the view and want to sit in the car munching a sandwich or something?

Actuallty, the more I think about these flap hand brakes, the less I like them.

It would be interesting to know when it is (a) Safe and actually desirable to use them, if ever, and (b) When is it dangerous to use them!

I mean does one _ever_ have to use them, or are they there only for show and reassurance, or some bizarre situation one would never face in practice.

They put the handbrake on manually by pressing the button.

I'm adding functionality not removing it. If you get out of the car the handbrake goes on. If you want to turn it on or off you press the illuminated button.

Speed, speed limits and stopping distances - Brake the road safety charity

The distances above are based on a reaction time of 0.67 seconds, which assumes the driver is alert, concentrating and not impaired. Driving when tired, distracted or impaired significantly increases reaction times, so the thinking distances above should be regarded as minimums.

2 seconds at 60 mph is about right.

0.67seconds=18m thinking distance

56m= stopping distance is 3.0555' * 18m.

3.0555' * 0.67 = 2.0472 seonds.
