I wouldn't be surprised if google acquired these guys to get into the space. Just imagine if it was tightly integrated with Android...and then imagine your google phone speaking perfectly with your google self-driving car. Oh the possibilities.
Exactly, building up this phone functionality is important to do now so that in 2-5 years we the public are more comfortable with the idea of self driving cars due to the incredible usefulness of blending the internet and analytics with vehicles (presented in a far less technical way, of course).
Imagine having an accurate trip-time estimate, adjusted regularly with information on which parking spots are available, and which entrance of a parking lot will have less congestion.
The high cost of driverless cars will make them take a while to catch on. But a cheap dongle can crowdsource this info to benefit us all.
