improvised temp fix? speedometer

[marshmello]

I realize I have been absolutely hammering this amazing forum with questions one right after the next but I am having a problem I just ordered the speedometer for my bike of eBay uk and I am pretty sure it's going to take a nice amount of time month? or more if worse comes to worse from what i've heard anyway so the dmv wont allow me to do the driving course until I have a working speedometer I'm wondering is there any temporary fix or anything I could do so that I can accurately measure my speed Maybe get a digital speedometer or something that is just temporary and doesnt really look like crud I am just trying to get out on the open road as fast as possible anyway thanks in advanced for any light you can put on this

Indeed thats exactly what i'm talking about.
Allot of people use this including me.
The price is usualy around 10-15 euros around here for the cheapest ones.
