The TDP's cities are laid out in a way that is repellent of cars, with the ground area having only walkways and bike paths, and the below ground area using only autonomous subway systems to transport people. Roads in the TDP are in rural and suburban areas.
The TDP is known for their self-driving cars that are illegal in some Taijitu nations, but beloved in others. The cars tend to come in radical shapes and sizes that are suited for very specific activities, such as sleeping, working, meetings, and more. There's no such thing as a "normal" car in the TDP. Non-autonomous cars are illegal in cities and in some suburban areas, though every major area has a racetrack on which people can drive at incredible speeds.
The infrastructure of the TDP is best described as all roads being a highway. There are no streetlights at all in the TDP, only some roundabouts in a few crowded suburbs, and simple branching paths in all others. This is to cater to the autonomous cars that the TDP has.
The TDP has a few car companies that are popular exports, especially in Delfos, Jutensa, and Myroria. Low-cost companies comparable to Toyota or Ford include Veval and Besta. Veval is considerably more popular in the mass market, but where Besta shines is in the luxury segment with their subsidiaries Caros - a brand comparable to Infiniti or BMW - and Beauto, which is comparable to Rolls Royce. Besta also has a subsidiary in Raroa, which is not a luxury company but instead makes high-performance cars made for racetracks and exporting to nations where self-driving cars are illegal. The last major car company in the TDP is Searco, which is comparable to Mercedes.
