Parking lots are extremely common sites for low-speed — but pricey — car crashes. Backing out of a parking spot, even with a rearview backup camera, can be a perilous exercise. That’s why rear-cross traffic alert is so useful.

Thanks to sensors built into the rear of the car, the system can alert you to approaching vehicles, shopping carts, or pedestrians who might wander behind your car without you noticing. Loud beeps are standard with these systems, but some cars can even automatically brake before a collision occurs.

Experts estimate that more than 750,000 motor vehicles will be stolen in 2019. While that number sounds alarming, nearly 46 percent of those vehicles will be recovered — and that number continues to improve. Much of the credit goes to innovative technology that automakers are building into their vehicles, such as the ability for the stolen car or truck to tell law enforcement when it is being held.

The technology is bundled into the vehicle’s assistance and security systems, such as BMW’s Connected Drive or GM’s OnStar. While those advertised features allow effortless diagnostics, concierge, and post-crash notification for summoning rescue services, they may also be used by law enforcement to pinpoint the exact location of a vehicle that is no longer in the owner’s possession. Criminals beware.

GPS tracking system that updates a vehicle’s position every 10 seconds. Watching it live requires only Internet access. Small and portable, the tracking device can be moved from vehicle to vehicle. It can also alert parents through their cell phone if the vehicle’s preset speed threshold is exceeded or if the vehicle enters/exits certain areas. It and similar LiveViewGPS products are also handy tools for businesses that need to track their fleet vehicles.

New technology, particularly the way cars’ construction is evolving, means that auto repair shops need to update their techniques and equipment. A specific area of concern is the increased use of aluminum in car design. Aluminum body panels were once a privilege reserved mainly for high-end performance cars.
