Tesla has rolled out a couple of very useful features, and it’s surprising it took automakers until 2019 to develop them.

These features use  the various existing sensors and cameras in Tesla cars to offer new safety and convenience options that owners should find pretty useful, Automotive News reported.

The first is Dog Mode.

This feature uses automatic sensors to maintain a comfortable temperature for pets inside the vehicle when you have to run errands, such as inside a grocery store, while also displaying a message in giant letters to passers-by who might become concerned for pets left in the car.

The message will tell anyone looking inside the car that the owner will return soon and display interior temperature.

This feature can be activated via the climate control menu, simply by pressing a button labeled “Dog” within the Keep Climate On option.

Back in 2016, Tesla already offered a Cabin Overheat Protection feature — a more basic version of automatic climate control for when the car is turned off.

Dog Mode is the upgrade, offering more user-adjustable settings, the report said.

Of course, this system is not a replacement for common sense or local laws, especially when it comes to leaving children in the car.

The second feature is Sentry Mode.

This will activate exterior cameras if it detects people near the vehicle and will display a message on the central screen notifying anyone who might be looking inside the vehicle that the car is using cameras to record them.

In case someone actually breaks a window, the alarm will activate, and the car will also blare music at the maximum volume setting, the report said.

Drivers will need to manually activate Sentry mode each time before leaving the car and plug in a USB drive on to which the car will upload the video.

According to Business Insider, the idea for Dog Mode seems to have come about after someone tweeted Tesla CEO Elon Musk with the idea in October.

The tech mogul, who like to includes quirks in his cars such as the ability to dance to the trans Siberian orchestra, simply replied “yes.”

However, some animal groups remain cautious, the report said.

A spokeswoman for PETA said that while Dog Mode is a nice idea, she would caution against using it.

“We thank Tesla for thinking about the dogs who lose their lives in cars every single summer, but we caution that the ‘Dog Mode’ function isn’t foolproof and could provide a false sense of security, as engines and air conditioning can cut out. The notice in the window telling passers-by that everything is all right is also cause for concern, as it might dissuade someone from intervening if the technology does malfunction. The safest way for anyone to protect dogs when temperatures soar is simply to leave them at home — with plenty of water,” she said.
