Drove few circles around Newbury/Thatcham to try out this long-awaited feature. Initial observations are:
- It is definitely useful. Not 100% accurate, but certainly step in the right direction. Hopefully Tesla will utilise our data to further refine the neural net
- Stop lines accuracy did not change. Most well drawn lines are spot on, but some worn out can be a bit out. Mini-roundabouts tend to be seen as stop lines, regular roundabouts are not observed as stop lines. Zebra crossings are not yet recognised in any way.
- Car will slow down and stop to any traffic light regardless of colour. It will chime when approaching green light. For it to go through green you have to confirm car observation with stalk or pedal. Normally chime comes in a good time when light is far enough and some seconds before car starts slowing down.
- This feature is useful when going straight through junctions. Not so much for turns, auto-steer/cruise control still freak out on most junction turns in town.
- It seems that a combination of cameras and map data is used to determine stop lines and traffic lights. Some traffic lights behind bends where clearly "expected" by the car before cameras could see them.
- On one occasion had an alert about road departure detected / corrective steering applied for no good reason. Road was poorly lit with some cars parked around, but still have not noticed this issue before.
- Traffic lights visualisation is now bright and juicy
All in all, for me 2020.36.10 is the most important update since I got the car back in December last year.
