Transportation

A typical civilian vehicle is an air car with a robot brain that uses multiple redundant contragravity field generators to float or fly. Propulsion is by manipulating the contragrav field to “coast” in the desired direction assisted by air jets for fine maneuvering. The vehicle is powered by battery charged by the local grid for continuous operation.
Vehicles intended for long term operation away from a civic power grid or handy recharging stations may be equiped with a micro fusion plant.
Contragravity is common safe-tech in the galaxy but the weight of the contragrav generators prohibits it from being wearable. The smallest contragrav vehicles are grav bikes and hover sleads.
Grav vehicles needing greater thrust replace the air jets with clean reactionless thrusters. Reactionless thrust requires more power than batteries can provide for more than a short time so these vehicles require power plants.
Reactionless thrust is also the galactic standard for starship sub-light drives.

Slidewalks, air busses, and maglev trams and trains are common forms of public transportation.
Hypersonic, extratmospheric shuttles are typical for fast travel across a planet or to orbit. Space elevators are slower and cheeper however.
High speed elevators, trains, and shuttle craft typically are equipped with artificial gravity with inertia dampers for the safety and comfort of passengers.
