HannesW,
Best use your Pi to program a Pico to do your tacho/speedo. Its lack of an operating system and modest power needs will save a whole load of grief triggered by un-managed power offs with SD cards.
It occurs to add that instead of an LCD display you could use a couple of simple step motors as used in many modern cars. At power up its just a question of parking their indicator needles at a zero stop.
