I disagree. A physical switch on the key itself which opened a circuit to the decryption key would mean the key would need to physically be in the possession of the driver.
- mikeash 8y ago“The idea” here refers to having the key operate automatically without having to manipulate it. If you require the driver to push a button on the key, the problem is trivially solved.
- raisedbyninjas 8y agoThis eliminates all of the convenience of keyless entry/start.
- askvictor 8y agoAnd what problem does keyless entry/start aim to solve?
- frankchn 8y agoIt is a convenience feature -- you don't have to fish your keys out of your pocket/handbag and press a button to unlock your car doors or to start the car. So long as you have the key somewhere on you (bag/handbag/pocket), you can unlock and start the car.
- mulmen 8y agoIt’s really pretty impressive too. I once tried (accidentally) to lock my key in the trunk of my car and it refused to close the latch.
- askvictor 8y agoIs getting your keys out of your bag or pocket really that hard? In comparison to the security risks? To think of it another way: before keyless entry was a thing - how many people were thinking 'damn I wish I didn't have to get these annoying keys out of my pocket?' To think of it yet another way: How many people buy the upgraded trim on their car mainly for the keyless entry? (Not having a go - genuinely curious)
- frankchn 8y agoLike with anything to do with security and convenience, there is always a trade off (longer passwords are more secure but harder to type, etc...). I don’t think this is a big enough security issue right now for car manufacturers and insurance companies to really do too much about. I used to have a car without this feature and it was sort of annoying for 5 seconds each time I have to unlock the car. I do get annoyed when I get a rental without this feature too. Additionally, this also helps when I am carrying bags or other large items with two hands. I can simply make a kicking motion at the bottom bumper of my car and the trunk will open automatically instead of me having to put the bags down and fish for my keys. I agree that it is minor and not a real deal-breaker, but it is a nice to have.
- altfredd 8y agoIsn't "keyless entry" basically same concept as "not locking a door"? You can trivially implement it on every vehicle without using any electronics at all.
- frankchn 8y agoUh, no? When you touch a door handle when the car is locked, the car will try to detect a keyfob near the door and then unlock itself when the keyfob is detected. The car won't unlock if a keyfob is not detected.
- alistproducer2 8y agoI suspect many people will happily give up such a convenience if it means they won't have their cars stolen so easily.
- huebnerob 8y agoYou suspect that the average person is going to give up a convenience that benefits them multiple times daily to ever so slightly mitigate the risk of an incredibly rare problem? I do not agree.
- zuppy 8y agoi'm a very technical person and I also wouldn't give up the convenience of keyless entry. that is what insurance is for.
- closeparen 8y agoThat’s what we had 10 years ago.
- alistproducer2 8y agoAnd apparently what we had 10 years ago was better as people couldn't steal your car without touching it.
