V2X trust

(cont'd from yesterday's post)

If V2X is to succeed, drivers must trust it. So designers have focused on two things that will certainly concern drivers (human drivers will have V2X before cars are self-driving).

1)  Accuracy
If drivers don't believe in the accuracy of warning signals coming from the V2X system, they won't brake or turn or whatever is called for - and they will not be safer. 

2) Privacy
If your car is constantly sending data about its speed, condition, location, etc., then it could potentially be tracked by government. (Americans don't want that, in contrast to Chinese who approve of 600 million surveillance cameras.)

More info:

• V2X will add about $250 to a car's cost
• Benefits will come when most vehicles are equipped with V2X
• Governments may require it of all vehicles by 2020
