Also, we should just get rid of the ignition keys for cars, since some of them can be hot wired.
On an unrelated note, whereabouts is you car?
You fail to understand the problem, in a car YOU have the key, with UEFI, a great deal of organisations (MS, BIOS vendor, MB vendor, HW vendors like Dell/HP/Lenovo/...) have the key to your computer - we dislike the fact that as the rightfull owners of those computers, we seem to be the only ones NOT having a key.
If you want a car analogy, it is more like not having a "key" for the filler cap, wheel bolts, engine,... You can start, you can drive, but you can not replace parts, use other fuel supplier, do your own maintenance. There might even be restrictions on where you can drive to.
