I feel that a 3G or 4G mobile device would do it for me. But, a car connected to the internet, road safety system, a traffic control system et al. sounds like a cool ride. Of course, the roads and the vehicles must be automated in my fantasy.
I'll play devil's advocate and ask the tough questions ... namely, what systems within a vehicle require an internet connection?
It's obvious that the driver would be unable to use the internet unless it had a voice interface, which it doesn't. The GPS/mapping software might use it, but the maps are usually preloaded so again, not needed. Traffic reports? I believe those piggy-back on the AM radio signals, therefore not needed. Only passengers could use the internet if it was present, but they could just as easily use a smartphone to surf ... assuming that they absolutely require the access.
So back to my original question ... what systems within a vehicle require an internet connection?
I'm with you on this one Larry. When my car wants to access the net, I would much rather that it use my 3G or 4G phone that's sitting right there. Nobody wants to pay extra for the car to have it's own data plan -- it should be perfectly capable of piggy-backing on the user's internet-connected phone.
The shift is when the car accesses the Internet, not the passengers. The question is whether the car has its own cell connection or borrows that of one of the passengers. Personally, I'd prefer the latter.
What's the big deal? You have a 3G or 4G phone, you have Internet in the car. Obviously, that's not going to be the best way for a driver to use the Internet, I mean a typical smartphone or tablet user interface, but in principle the link already exists.
Works fine. My son-in-law does all sorts of looking up online, while we drive places.
