No need for that, any EFI vehicle at the very least can be stopped with existing EMP devices. With enough disruptive power anything but an MFI diesel can be stopped.
No I'm pretty sure I've heard and felt the lock click while the key is still inserted but in the OFF position. I'm going to double-check on my vehicles later.
Yes it's too bad that it's so easy to skip over ACC/1 straight to OFF. Some cars require the key to be pushed in to get to the OFF position, I thought that was a good idea, too bad more cars don't have it.
Wrong, synchros mean you don't have to double-clutch, but you still need to rev match (the heel part of heel-and-toe, or you can do the similar but slower sidestep maneuver) if you don't want a shock of engine braking when you downshift. That said it's not a technique that's really needed on the street. In racing it's used to downshift without transferring weight forward.
Dual-clutch? Those are horrifically expensive supercar transmissions. I think the term you're looking for is robotized manual (which is still more expensive up front).
Given that electronic fuel injection systems really only use a pedal sensor rather than an old-fashioned accelerator linkage moving an arm on the carb, it should be quite easy for a tap on the brake to override the accelerator inputs.
Wrong, most EFI vehicles still use a throttle linkage just like the carbed vehicles. Fuel can be cut electronically though.
Only some of the latest cars - mostly ones with robotized manual transmissions - have e-throttles.
Ignition cut won't cause any damage. Worst case scenario, if it's a carbed car with a mechanical fuel pump and you keep it in gear, it might send unburned fuel through your engine and wear your piston rings a bit.
Have you ever used one? You can't apply much braking power to the rear wheels of a vehicle before they lock up if you're moving forward. And as a cable-operated brake, you can't apply anywhere near as much pressure as with the foot pedal.
Are you using left-foot braking? From what the GP said it shouldn't be a problem unless you're using both pedals at the same time. That's not even helpful in most forms of racing.
Yeah that would be quite a PITA. Although if you're good and the vehicle has plenty of low-down torque, it's possible to take off even on a very steep hill without using any braking with little to no rollback, but I'll admit it requires near-Walter Rorhl-level footwork.
With the Lexus that crashed you had to hold the starter button down for like 10 seconds while the engine was running to force a shutdown. During a panic that would have felt like an eternity, it's understandable that he didn't figure it out. But doing away with the ignition key switch is just a bad idea anyways.
If you have vacuum-assisted brakes, there's typically quite a large reservoir. Try it yourself; switch off your car's engine (while you're stopped, obviously) and pump the brakes a few times. You should get about 5-10 presses before the pedal starts to stiffen up.
Even when you deplete this, it's just as easy to stop a vehicle with unassisted brakes once you get used to the massive amount of pedal pressure required. It's not a feat of strength, just way more than most people are used to (especially on modern ABS-equipped cars with hypersensitive brake pedals). A lot of race cars have unassisted brakes because some drivers prefer the slightly finer control over the much lower physical effort.
Turning off the engine with the car still in gear could damage the gearbox and/or engine
That's definitely not true in the case of a manual vehicle and I'm pretty sure it's safe in an auto as well. Yes the engine will be driven by the wheels, but it's not bad, it's called engine braking, and in fact in an EFI manual vehicle is identical to the state of engine braking when the engine is running.
On every car I know the steering wheel lock engages when the ignition is in the OFF position, whether the key is in or not. What car do you know that works as you said?

This is what's done in racing.

. First ABS that can't be switched off to make sure you can't purposely lock up the brakes.
Install a switch inline with the ABS system fuse, or just pull the fuse if you never want the ABS enabled.

Yeah muscle cars with monster engines and sorry little drum brakes will still move, but anything with any disc brakes on it should stop quite easily.

The same way, just requiring more force when the engine is shut down?
BTW hydraulic brakes are unaffected by engine condition. I think you mean vacuum-assisted.

American spotted, doesn't even know what a clutch is.
Even if the throttle is open the brake booster vacuum reservoir still holds enough for a few pumps of assisted braking.

Lose all control? It's still steerable, it just requires more effort, at high speeds you may not even notice the loss of power steering.

They make them without pivots now? I'm so glad my cars are old.
I have '91 and '95 cars with an engines designed in the mid-'80s that have no artificial limiters or electro-nannies of any kind.
They're fired by an electronic sensor system, but that's always on unless the battery is pulled AFAIK.
The handbrake's for bootleg turns. You drift using the gas, perhaps initiated with the foot brake in some situations.
