Start button takes its sweet time

lol very true (15sec too). and the audio and video are usually recorded separately.

There is not a direct connection between the starter button and the engine. The button is depressed and the signal goes to the computer. The computer then checks to see if everything is a "go" and then the signal is sent to the starter. After about one second, the car starts. Mine does this as well, so I don't think there is a problem or anything that you can do to speed up the process.

So, the speed of light is too slow?

The car and your key-fob do an encrypted RFID handshake. This involves passing of public/private key pairs with known lists of "correct" challenge/response pairs. This involves quite a bit of back and forth between the key and the car, as well as range verification and such. This isn't the entirety of the extra time needed, but it's a chunk of it. I'm sure the rest is the ECU checking vital sensors/systems before startup.

It's a disadvantage to not having a physical key. With a physical key, you don't need encryption, as the key itself serves as the same layer of protection as the encryption. Thus, physical key = much faster.

I agree. When I use my battery operated key on her, it takes longer than my physical key does.
