I am hoping Tesla incorporates (if they haven't yet) these ideas in their new cars.
What do you want to see from tesla?
Custamizable interior lights/floorboards
Customizable heads-up display on windshield
Customizable sounds (turn signal, etc)
Voice welcoming/acknowledgement through fingerprint recognition in steering wheel
Heated or A/C seats
Customizable dashboard/blind spot monitors
Transition Lenses on the windshield
Friend follower-tesla cars can recognize each other/who is driving and you can link up if you are trying to meet somewhere/follow each other somewhere w/o getting lost in traffic
Consciousness recognition-actively tries to get you to respond and calls for help when you don't, autopilot to the side of the road if you experience a seizure or fall asleep etc
Silent alarm-if you get attacked next to your car, GPS can follow your key fab to lead to you if you get abducted (phone app?)
What else are you hoping to see?
Towing capacity (Tesla model Y=truck=S3XY)
