Even if there are personalised self-driving vehicles, there will still be a need for public transportation, and that's where the high-speed bus designs come in. The MACH bus is aerodynamically designed to prevent wind friction and is powered by hydrogen fuel. It features a fluid suspension system to keep the ride nice and smooth. Because the bus will be traveling faster than most other vehicles, its safety features are enhanced, including having active and passive safety monitors and controls, meaning it's always alerting the driver of potential hazards. To keep it light, the bus has been built on a carbon-fiber chassis to maximise strength and minimize weight. And of course, it's red, just like the old-school London double-decker buses.
