The proposed feature would display the cabin temperature to reassure onlookers the dog is safe inside.
Pet owners rejoice: Elon Musk has hinted on Twitter that future software updates could add a 'Dog Mode' to Tesla vehicles. Potentially, the feature could tell passer-by's that the dog inside the vehicle is safe and not overheating and that its owner will return shortly.
When a user Tweeted Elon Musk requesting a 'Dog Mode' feature in the Tesla Model 3 "where the music plays and the ac is on, with a display on screen saying 'I'm fine my owner will be right back?'" the CEO replied with a simple "yes" answer, implying the feature could be added in a future software update.
Another user suggested displaying the current interior temperature on the screen to reassure onlookers, which Musk agreed would be a good idea. Tesla has already released a software update that prevents child and pet heatstroke with its Cabin Overheat Protection feature released in 2016 that automatically regulates the cabin temperature.
However, even though the air-conditioning stays on when the car is switched off, a passer-by could still see a dog in the car and be concerned about its welfare. Adding the proposed Dog Mode seems like a simple way to solve this problem, as there have been many cases where worried onlookers have smashed car windows to rescue a dog seemingly suffering inside a car even though the air conditioning was on and the owner wasn't gone for very long.
