Is it not normal for a keyless car to beep like crazy when you leave the car with the key inside?

My car does this. As soon as it detects the key is not inside the car it will beep and remind you the car is on. The other problem this solves is that you don't want to be driving somewhere without the key either, eg when you're dropping off your wife and she happens to have the key.

Same, and exactly; the car should just shut down when it detects the key is not inside the car. Could someone just get in and drive off?

I'm fairly sure this might be true for older models though.

This is quite dangerous going down the highway at 55mph when a GPS jammer malfunction causes the fob to 'disappear'.

The keyless car I owned would warn and beep like crazy about the key missing, but it would continue driving. Then when coming to a halt and shifting into neutral/park it would deny switching back to drive. So no danger while driving and no risk for stealing.

My Honda CR-V will periodically beep with "NO KEY" lighting on up on the dashboard(say I give my wife the key to get inside our home on a crappy day while I go park the car elsewhere), but doesn't make impose any restrictions on using the car while it's on, regardless of your current speed or gear. Once you shut the car off though, that's it.

Well, you can't have the car shutting off if the key is suddenly not detected. The battery might be low, or the key gets dropped behind some metal. But it does mean that after you've turned it off you are stuck there.
