Tesla pushed an over the air update that include a feature call 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 that the owner will return soon and display interior temperature to passers-by who might become concerned for pets left in the car. This is good for dog owners who bring their pet with them and had to make a stop somewhere real quick during hot or cold weather. In addition with the message being displayed passerby might be less worry about the pets inside the car, and won’t have to get others involve to break into the car to let some cool air in.

I find this very interesting. Leaving dogs unattended in a car has been an arising problem recently. Tesla has definitely taken advantage of this opportunity. However, isn’t leaving dogs unattended in a running car mean the dog owner is irresponsible? This implementation might influence Tesla owners to leave their dogs often since they have this new feature to rely on. I am definitely confused whether to praise Tesla or wag my finger at how they are making humans lazy.
I’m always amazed by Tesla. The other day I was having a conversation about how five years ago I never thought they would take off but now they are a major player in the automotive industry. By adding small features like this, Tesla differentiates itself from competitors and sets trends in the market. Just a few days ago, Tesla released romance mode for Valentines day. It displays a fireplace in the center infotainment screen and plays love songs. Both modes show the advantages of being able to send updates to all Tesla vehicles.

I agree with everyone saying Tesla is brilliant at solving problems and this feature may be small, but it will provide relief for people passing by the car and seeing pets inside. This will benefit both pet owners and regular pedestrians as the owners will know that their pets will be perfectly fine inside the car while the owners are away. Also, pedestrians will not break the car’s window to ensure that the pets are comfortable inside.
