Interesting. On older tesla cars, people complained about the maps and the older MCU1 cpu.

The telsa maps are based on google maps.

I heard there were two ways to speed up maps:

1) turn off traffic, which significantly slowed things down

2) switch from vector maps to satellite maps. Apparently the map tiles of the vector maps require costly rendering for display, but the satellite maps just required a blit.

#2 may also explain #1, I'll bet traffic requires rendering too.
