NASCAR: Sprint Cup stars in Pennsylvania, Nationwide Series runs in Iowa

NASCAR's three-race, two-venue weekend has a somewhat different face now that Carl Edwards has re-signed with Roush Fenway Racing and Brad Keselowski has been told to skip the weekend's Nationwide Series race in Iowa. And what's with those big-time Sprint Cup stars running the Camping World Truck Series race at Pocono Raceway? Edwards is at Pocono all day Friday and part of Saturday to prepare for Sunday afternoon's Good Sam Emergency 500.

Planning continues for driverless cars

OFFICIALS in California have been looking to the future as they bid to legislate for the arrival of hi-tech driver-less cars. A law passed in 2012 set a deadline of the end of this year for the state's Department of Motor Vehicles to decide how to legally integrate the so-called autonomous vehicles - which were once the stuff of science fiction but could be commercially available by the end of the decade. The latest talks on the matter among roads officials focused on how the vehicles will record actions so the data can be used to reconstruct an accident in an effort to trace the cause.

Two LaFerraris test at Fiorano Circuit

We don't need to say much about this video of two Ferrari LaFerraris testing at the Fiorano Circuit in Italy --caught by spy videographer extraordinaire Marchettino --except for “turn it up to 11.” In fact, we recommend you use a headphone-to-RCA converter and plug it in to the loudest stereo you have. That's the only way you can truly appreciate the Italian-opera wail coming from the 963 hp, 6.3-liter V12 as it boogies around the 1.8-mile, 12-turn test track. Marchettino said the camouflaged car must have a different exhaust because it sounded so much louder.
