Audi is going to be the first company to integrate a feature we think should be available on all cars, a vehicle-integrated toll payment system. The system will be available on their upcoming e-tron electric crossover and will integrate a toll transponder into the vehicle's rearview mirror so you won't have to ever deal with a separate, unsightly module. It will also feature wide compatibility that allows for payment on tolls roads across North America, which will include the US, Canada, and Mexico.
