Cars that Talk to Hit the Market: Will this concept work?

Cars already do that. Cars already tell you if there is a car in your left you cant see. It can tell you you forgot your key in the ignition. It can tell you the lights are on when you leave the car. It can tell if you didn't close the doors properly. It can tell if you jump lanes. Cars can already to a lot of that.

Infact there are cars in the market already that can drive itself for over 80% of the distance.

I really don't want a lady voice tag attached to the car, to shout at me every time i do a mistake.  Its very distracting and annoying at the best.

We already have technology in place wherein the automobile interacts with the passenger depending upon various external inputs & surrounding. With time these will be intensively used to enhance safety & emergency services. It will be more of use on the highways wherin the transit speeds are very high & many times we need more inputs than just our vision to make split second  decisions. But i doubt if the same will be usefull in cities ( till the time same has been incorportated on all ( e.g. trucks, autos, buses etc)

Dear Mr. Prakash, you are right, indeed, in these type of cars there will be "Audible signal" with "pre-recordable" message about fuel level in place of visible indicators. Also, if this process has been introduced, it will be a very well adopted in cars. I think this process might work...

According to me I think this concept will work out and in todays scenario there is no end to what is called Luxury and a car that can drive itself and can talk will fit the bill perfectly for many, but then ofcourse cost would be a problem, as this sort of technology cannot be used by common man, the price factor is the problem in new innovations if this technology is developed in a way where it is available for all this could prove very useful as there is Accidents happening every now and then so interms of safe driving this technology would be handful.
