As someone else pointed out, Futhark can be compiled into a Python program or library that uses PyOpenCL. For some "ecosystem" uses of this, you can look for the 'futhark' tag on GitHub:
What about computer-controlled bicycles? They can probably react faster than humans, meaning less accidents! You only have to do the pedalling, and the computer will handle the rest.
Better to let the propulsion be handled by small electric motor and use the (optional) peddling to charge the batteries. This way the human doesn't get in the way of hitting the optimal speed and acceleration.
