Sure, it's cutting off their noses to spite their faces.

<br>
Quotes:<br>
The real magic here is the algorithm that manages AutoRally’s steering<br>
and throttle. Rather than hierarchically splitting control and<br>
planning into two separate problems, Georgia Tech's algorithm combines<br>
them by integrating vehicle dynamics in real-time. Generally, this is<br>
a very computationally intensive approach, but AutoRally can calculate<br>
an optimized trajectory from the weighted average of 2,560 different<br>
trajectory possibilities, all simulated in parallel on to the monster<br>
onboard GPU. Each of these trajectories represents the oncoming 2.5<br>
seconds of vehicle motion, and AutoRally recomputes this entire<br>
optimization process 60 times every second.<br>
--------------<br>
<br>
The video is six minutes long and shows some crashes during testing<br>
after the five minute mark.<br>
<br>
This should make robot racing cars produce much more human-like driving.<br>
(Though not as many crashes as humans!). :)<br>
