How does a car measure the outside temperature at speed, without it skewing for windchill or engine/surface heat?

They don’t very well, the ones on planes have to be adjusted for speed because the friction of air hitting it while moving warms it up above ambient temperature
The best bet would probably be placing it in the shade away from the sun on the lower side, away from hot components and placing it somewhere with only incidental amounts of air movement. Alternatively there could be a tube designed to capture no air movement at all regardless of vehicle speed – that then turns on a fan blowing through the tube at a known speed while measuring
