Sounds like it is better than useless, but not by much.
A higher priority should be introducing technology to automatically mute all in-car appliances when in the vicinity of level crossings and school zones. already pretty standard feature for in-built SatNav.
It should be very simple to implement through the use of roadside beacons rather than the device location. Mandatory installation on new cars and a discount on registration to incentivise retro-fitting on older cars.
2016 model feature on Hyundai. Doesn't get more basic than them.
Approach to school is mute radio or phone to announce "Tool zone ahead" several occasions.
Ditto for other important warnings
Built-in satnav is a transitional technology which is on the way out, and it will be a positive to have everything mute automatically regardless of whether the satnav is in use.
there is really no way to please some people. Answer a question and you just get sneered.
SatNav is A
feature of the in-built electronic control systems pretty standard these days in most cars.
Matter of whether you pay the "upgrade" version to have all the other bits turned on.
What with SatNav, lane assist, park assist , self park, brake assist, "can I fluff you pillow" assist
all that is needed is a software upgrade for self drive. (which sometimes I could do if brave/silly enough to let go of the steering wheel)
As for "transitional technology", how do you think that self drive cars will know how to get there?
I'd like to see Robby the Robot with a Melways on his lap.
Auto mute and warnings can be effected whether navigating or not. Just needs to be turned on even with the screen blacked.
These are BASIC FUNCTIONS.
Really need to look around, systems have evolved dramatically in the last 5 years. Lord knows what next years models do.
