  • The two red lines are at a right angle, you can connect them and solve for the hypotenuse using the normal a^2 + b^2.

    At this point you now have a second triangle that contains the X you want. Also, since the outer shape is a quarter-circle (assumed) you know that the corner in the bottom right is 90 degrees which makes the two side equal in length.

    Since it’s an equilateral triangle, and you know the hypotenuse, you can back it out with c^2 = 2a^2 and solve it that way.






  • Something else that people don’t think about besides the backend server is the connectivity. A lot of these cars use LTE with eSIMs that can’t be replaced, and getting an internet package for it will be next to impossible since Tesla gets them at bulk rates. Once upon a time cars did allow “bring your own SIM cards” but not anymore. Also as cars get older the cell networks get shut down. Some companies did offer upgrades but that was few and far between. Most just said “sorry, you’re SOL”.

    So even if you could hack your car, your car won’t have any way of talking to a custom endpoint.
