Has anyone compared the rates of carbon monoxide poisoning with and without keyless ignition? I could actually see an argument for keyless being safer: if people can leave a car and completely forget to turn it off, they can certainly do that and forget to take the keys with them. At least with the keyless ignition you have the _possibility_ of being alerted to your mistake (my Toyota beeps so loud that it would be pretty much impossible to ignore).
