And yet I was replying to a post from someone who said it hasn't worked for them on more than one occasion. It is still careless of Tesla to leave the effectiveness of their car keys to a constantly changing device they have no control over. What makes it a "great feature" for you though? Is it that you don't have to carry a small key fob in your pocket?Eh, most people will tell you this is one of the best features of the car. It works most of the time for most people and when it doesn’t, toggling Bluetooth or reestablishing the phone as a key fixes nearly all issues.
Everything outside of that is an edge case for a great feature IMO.
