Can handheld cars automatically start the car, automatically turn on the air conditioner, and automatically heat the car through text messages?

SIEVAL: No! The vehicle must be started to automatically turn on the air conditioner and automatically heat the car. Remote starting of the vehicle involves serious safety and legal issues. Riders who know a little bit about technology may say that the equipment can detect whether it is neutral, whether it is handbrake, etc., which may not be understood by riders. These detections are not at the same level of security as the consequences of remote boot. Remote start is technically very simple to implement, so in order to please consumers, some equipment manufacturers provide these functions and use them as a selling point, which is an irresponsible behavior. I hope everyone will love themselves and respect life.
