Yes. It's called Qual Comm. I had one on my truck. It also monitors if a trailer is attached to the cab of the truck or not, the speed of the truck, it's idling time, current inside and outside temperatures, the works. Most companies use it as a tool to keep track on their drivers and make sure they're driving the full 12 hours per 24 they're supposed to. However, this isn't the system in question...
Just like your home computer, if you deploy a technology such as navigation to a public medium like bluetooth and the internet. What would we expect? At present the cars are using computers to drive the engine and break systems. But navigation and internet access is not part of that, and probably never will be. Except where already applied by mass transit. Sophisticated trucking companies use position data to adjust fuel ratios into the combustion chamber. For example when they are rolling across the great planes of the USA they can have their fuel mixture backed off via a GPS system and when they reach the high plains and then Denver the fuel ratio is adjusted accordingly to enable and increase in forward momentum. This saves a ton of fuel. But it is also not public. In fact it's a sat channel.
For how much longer?
Not many ambulances or firetrucks use on board navigation.
What an amazing thing... I distinctly remember seeing and riding in 747's back in 1974. I'm sure they were flying earlier than that as well. I also distinctly remember they were touted (just as today) as the 'safest form of travel.' I also seem to remember there were less crashes...or less crashes we heard about at least.
As for taking a step back... Air travel would not be safe without computers. In fact modern flight models would not be possible without a computer making tiny correcting adjustments to airflow over it's surface.
I won't argue this with you. The antilock braking system is a wonderful thing. I'm curious though with the advent of these public-accessed navigation systems how much longer it will be before someone figures out how to crack them?
Cars are also much safer, anyone who has had antilock breaks, or traction control knows what I mean.

The day they computerize my toilet is the day I truly believe they've gone too far - and the day I build myself an outhouse. :D
Untill your t.v., fridge, toilet, shower, car, and clothes are all talking to eachother and all have some type of virus its going to keep on getting worse.
