Upgrade the kernel of the Prius.
Use one of the kernel performance measurement tools.
Upgrade the prius_mileage package (yum update prius_mileage).
Someday, the Toyota Prius might really run Linux. Cars, after all, have got onboard computers at least in the form of Engine Control Units which are getting pretty common these days. Particularly on high-end luxury cars, these onboard computers are also getting rather complex, controlling and monitoring a lot more things than just engine operation.
It wouldn’t be too long before cars start malfunctioning due to buggy software.
Oops. Actually some cars are already malfunctioning due to buggy software.
Not the least of which is, coincidentally on the same day, news of the massive recall of various models of Toyota vehicles in the US, including the Prius. It doesn’t sound like a software bug though, even though software could perhaps fix the problem.
