Some still riled by idling patrol cars, others say give ’em break

QI can’t believe some people are upset over police leaving their patrol cars idling while on a break. These cops are there to serve us when we need help. There are far more issues of far more importance. Cut the cops some slack.

ACops leave cars idling to allow computers to stay powered and make sure communicat­ions are not interrupte­d.

QI was surprised that the two locked police cars idling in the parking lot while the officers were having coffee at Starbucks didn’t get more of a response.

I suppose their excuse of wanting to return to a cool police car and not having to reboot their computers can be chalked up to progress in police work.

Back in the 1960s when I was an officer, there was no air conditioni­ng in patrol cars. We didn’t even have the advantage of their “wool blend” uniforms. Ours were 100% wool.

We did get by without

a computer in the car, mainly because at the time computers were the size of a refrigerat­or, and Steve Jobs was still in middle school.

I’m not sure how we managed.

I do hope today’s police cars are still equipped with radio communicat­ion with dispatch, so calls can be received in case the computer happens to be rebooting.

However, I did note another area of progress in that they were having coffee at Starbucks and not a donut shop.

Maybe even a latte. — Bob Morrison Sunnyvale

AYes, they have radios. Some officers also use cellphones to avoid calls being overheard by the bad guys. And the armor vests they must wear are terribly hot. But lattes are more popular than a jelly-filled doughnut.

QIf cops were driving Teslas, there would be no need to idle the car interior to stay cool to protect electronic­s, modestly draining the battery by about 1 mile of range per minute on a hot day. A Model 3 can easily outrun

almost any car a lawbreaker would be driving.

ABut the worry is the range an electric car would have when patrolling city streets before needing to be recharged. A 2014 Model S 85 can go about 265 miles on a full charge. Fremont officers drive up to 100 miles per shift.

QIt was shocking to learn police cars have to stay idling when parked even when no one is inside the car. I read a while ago Fremont is converting a used Tesla to a police cruiser. How has that worked out for them? — Carl Koo San Jose

AThe Tesla is now being tested. We could have results by early next year.
