Roseville police report two cars left running by their owners were recently stolen.
The first theft occurred Nov. 8 when a resident in north central Roseville left his 2003 Dodge Ram pickup warming up in his drive way about 6 a.m. A big guy in a hooded sweatshirt jumped in and drove off in the truck.
It hasn't been seen since.
Then, on Monday, in central Roseville, a motorist left his 2012 Toyota Camry sedan running in front of his office on Pacific Street. He momentarily went inside, returning only to see somebody driving away in his car.
His car is still missing.
"If you must park outside, never leave it unattended with the engine running," warned the police in a public safety newsletter.
National Public Radio Car Talk auto experts, Tom and Ray Magliozzi, say there is no need to warm up today's cars.
"On modern, fuel-injected cars -- basically anything made in the past 20 years -- you're not helping the car at all by warming it up for five or 10 minutes," said Ray Magliozzi on the brothers' website.
