like the trunk which opens automatically when you put your foot under the car and you are nearby. This is just a big gift for thieves, just wait for tourists with a car full of stuff to leave their car, stand in the vicinity and put your foot under the car when they leave but they are still near enough to allow the trunk to open...
Awe, isn't that cute, you're talking about shit you know nothing about.
In order for that trunk to open, your key has to be within about 1/3rd of a meter from the trunk lock or it doesn't open, so if I'm close enough that you can get into the trunk that way, I'm also close enough to just beat your ass for trying, since you two are going to be well within my striking distance at that point. You'd be hard pressed to get your foot under there with me close enough because I'm going to be in between you and the sensor or the sensor is going to ignore you.
And by the way, that sensor ... its a kick button, not just an IR pickup or something.
Same for the doors, you have to be within about a foot of the door. You can't unlock the doors from the outside when the key is on the inside. You can't unlock or open any of the doors with the key at or more than a meter away from the door you're trying to unlock.
You're missing the point here. They know how to deal with keys reasonable well, this is not new. In fact anything that requires physical presence they are generally pretty good with these days. There isn't a lot new here even if you think keyless entry is, it isn't.
They don't know shit about dealing with radio connected cars that can be touched by people anywhere on the planet. THATS why this DAB thing is a possibility, previously the only people who could 'hack' the car, were physically in contact with the car, which is an easy problem to deal, Smith & Wesson sells a product for this. What they can't deal with is when some random person somewhere far away that you can't see or detect until your left front wheel locks up because someone remotely commanded the ABS/TCS system to lock the wheel. No one in the car would do that because it's dangerous to them. The dude sitting in his chair miles away? He'll do it because he's an arrogant prick that thinks he's special cause he downloaded some hax0r app where someone else did all the work and doesn't realize that being a script kiddie just makes him a douche, not powerful and impressive.
