Anyone remember the days when you used to put the key in the ignition?
The only exception is if I have full control over it, including the ability to lock it down. No OTA updates; if I want to install security patches, it'll be through Ethernet or USB or some other wired connection. But preferably, there wouldn't be a whole lot of software to update in the first place.
That seems to me to be far more secure than a modern tesla.
There's far less chance of leaving your key in the car if you have to press the lock button on the fob after you get out -- done that on hire cars before. The key is always in the same place.
Conversely you can leave the key in the ignition if you're popping into the store to pay for the gas and leaving your passengers in the car. I had a keyless fob on another hire car in my pocket, alarm went off when I went into the store.
I don't get the appeal of keyless.
