We got a rundown of updates that Tesla has rolled out to existing Model 3 owners, and found five new features that new buyers can also expect. We got a first drive in a 2019 Porsche Cayenne E-Hybrid, to see what all the fuss is about. And our followers weighed in in our Twitter poll to let us know how often they want to see us cover the monthly plug-in sales horse race. All this and more on Green Car Reports.

In its first few months on sale, the Tesla Model 3 has already received updates from easier keyless entry to automatic high beams, as well as several changes to make its controls simpler.

After a reader alerted us that he couldn't buy a Chevy Bolt EV outside Toronto because the car was backordered for a year in Canada, Green Car Reports confirmed that it wasn't an isolated incident. Meanwhile, our reader decided to go with a plug-in hybrid Volt instead.

We asked our Twitter followers last week whether they actually keep up with our monthly plug-in vehicle sales reports, or whether running them less frequently might be acceptable. It wasn't surprising that continuing the reports was preferred. What was surprising was the degree of support they received in our Twitter poll results.

Keyless ignition systems that make it convenient for drivers to start their cars may make it so convenient that they forget to turn them off. Several people have now reportedly died of carbon monoxide poisoning after they didn't realize the cars were still running.

Finally, we learned that Audi will not bring its Level 3 self-driving technology to the U.S. when it rolls out its updated A8 luxury sedan next year.
