Q: Whoever told you that 8 percent of cars in the diamond lane is clean air cars is full of it. It’s more like 50 percent during commute times on Highway 87, Highway 101 and Interstate 280.

Shawn Phillips

San Jose

A: You are among many disbelievers.

Q: I find it hard to believe that only 8 percent are electric vehicles. I ride a motorcycle on my commute on Highway 101 from San Jose to San Francisco. There is a hell of a lot more stickered cars — more like four of every eight. … Where did you got this information that only 8 percent of those in the carpool lanes are electric vehicles? Anyone that drives carpool lanes would disagree. Prove me that I’m wrong.

Colette Aragon, Manjul Gupta, and others

A: This information came from a report from the Metropolitan Transportation Commission and is based on statewide data. But the Valley Transportation Authority conducted a study this year on how Express Lanes are working on Highway 237 and found that an average of 36 percent of all vehicles on westbound 237 during the peak morning hours were clean-air vehicles, and 30 percent of all vehicles in the eastbound direction during the peak afternoon hours were clean-air vehicles.

Q: I might believe that the overall state level of HOV lane use by electric or stickered vehicles is 8 percent, but that’s not at all accurate around this area. At least on Highway 85 from I-280 to De Anza Boulevard. I have been counting them and it’s well over 50 percent.

Alan Arndt

San Jose

A: You have a good point. Vehicles with clean-air stickers zoom to 18 percent in Silicon Valley and 38 percent in the nine Bay Area counties.

Q: I have bought my last two Prius’s after your feedback, so why break a good habit.

I am planning to buy a Model S but I need clarification on the HOV sticker eligibility considering that this is a 2017 purchase. Most websites are reporting that stickers issued now will be good until 2022. Is that your interpretation, too?

Rupa Srivastava

A: Yes, it is. Stickers on cars purchased through 2019 are good until 2022. Stickers on vehicles bought after that are good for three years. The carpool perk ends in 2025.

Q: Hopefully, people noticed the improvements that have been made with funds from the new gas tax when they did their Thanksgiving drives. I drove up to Redding and noticed several stretches on Interstate 5 were resurfaced. Maybe when people start to see improvements on their drives, they’ll calm down.

Taylor Howell

A: And maybe they’ll stop calling me a schmuck.
