Cars are a fairly boring topic for me, but I just sat through this 15-minute documentary by Audi completely enthralled by the amount of dedication the Slots Mods team poured into making an iPad-controlled slot car race track utopia for Audi.

Basically, Audi asked Slot Mods to make an iPad-controlled slot car race track that would give people the experience of driving an Audi from their iPad. You can control the speed of the car from the iPad and a little video camera behind the windshield shows you what it’s like to be the driver. The concept is cool on its own, but the amount of details and obsession poured into the project make it truly enthralling.

Hyundai is set to showcase a number of new vehicles at the Consumer Electronics Show in Las Vegas this week, and the company has announced that they’ll all include Siri Eyes Free technology. The feature allows iPhone owners to perform a whole host of tasks using the intelligent assistant — such as taking calls or creating Reminders — without taking their hands off the wheel.

General Motors has announced that its upcoming Chevrolets will be the world’s first cars to offer “Eyes Free” Siri integration, allowing drivers to use the voice control capabilities of their iPhone without taking their hands off the wheel. The feature will be integrated into GM’s MyLink infotainment system.
