Audi Urban Purifier's turns autos into Roombas. Neat. Also, I'm wondering about tires which pollute less. Both in their production and usage. To reduce particulates during use, I'm guessing tires will need to be tougher, less grippy. So might require better active suspension and braking systems to maintain current comfort and safety standards.
