Because you need to register for a myAudi account and provide the VIN number for your vehicle to use Facebook and Twitter services, we can only guess how well it works. But we do know that you can supposedly post updates to either social network while on the move, if that sort of thing floats your boat.
We're not entirely sold on the premise, but if it stops people from checking their smartphone when at the wheel we're all for it. Ultimately, that YouTube cat video everyone keeps talking about can wait until you get home, surely?
There's always a danger that cars with too much technology can bamboozle drivers and therefore make driving more dangerous, but the Audi A3 Saloon's infotainment system was easy enough to use that our attention remained on the road ahead. Minus the somewhat odd addition of Facebook and Twitter, everything was there to benefit the driver, making it useful for just about anyone behind the wheel.
As to whether you should buy the Audi S3 Saloon or the new Audi S3/Sportback, well, that's for another review...
