Would it be easier to do by using engine RPM rather than speed?

Does your car have an ODBCII port?

If you are new to all this then get a ODBCII port reader. I use the Freematics https://freematics.com/, had not one problem at all with using it.

You can then ask the car for its RPM’s, or speed, or whatever else is available for asking, with a MCU plugged into the Freematics, and light LED’s based on your programmed set conditions. Gets you up and running quickly and not such a high learning curve as making CAN buss thingies from scratch.
