DrivesTV brings us a new video of the BMW autonomous Runway Trainer 330i doing some laps at Laguna Seca. The BMW Rail Trainer is designed specifically to help drivers develop avant-garde rail driving skills by being shown the correct way effectually the track with correct lines, braking points and turn in.

It features three modes, the offset being democratic, where the motorcar controls the driving, the second uses sequences of lights to show the correct turning points and the third records the commuter's inputs and allows them to be replayed later for analysis and coaching with a professional person driver.

The democratic car is built on the standard production of the 330i model, simply the software underlying the vehicle is quite special. Utilizing a combination of built-in GPS, a signal booster and accompanying repeater (increasing bandwidth and accurateness down to the centimeter), a custom map of the track and a trained commuter to prove it the optimum racing line, the Runway Trainer learns the course and tin can show budding racers how to do it right.

The software is fabricated out of complex algorithm to determine theoretical grip, while wheel speed and spin sensors send data to the computers to interpret the exact amount of suspension load, power commitment and braking strength necessary to keep information technology out of the weeds. A driver feedback display mounted on the center console shows drivers how close the car is to the optimal line while in control.

It its lifetime, the 330i Track Trainer has already accumulated 12,000 miles of testing.
