I’m looking for pc or android map software that is limited to roads with a speed limit of 35 or less
Or you add an AC motor, controller, and lithium and run 50+ mph… lol
Don’t know that I have ever paid attention to the true speed limit. 
Seriously, that is a good question. We have all kinds of route planners for our Teslas and EV’s but I can’t think of any that have options for low-speed roads…
I’m not worried about how fast I’m going
I am concerned a cop short of their quota making an example of me…
There is the possibility of getting the city & or the county to give me a grant to do the work
