changing sprockets makes speedometer invalid?

I have repeatedly seen comments on here about different sprockets and how the odometer is inaccurate. I'm confused. The sensor is on the front wheel -- how would running different sprockets change the validity of the odometer? Or am I confusing this with changing front wheels?
Reason I'm asking is that I need to replace the sprockets & chain on my street bike. I have a whole 520 kit with a 45 rear sprocket sitting here. Is going from a 44 stock to a 45 rear going to affect my speedometer accuracy? I'd rather not, as I currently live in Sunnyvale where cops are *BORED* and are known for giving tickets for 5mph over.
Yes I know the speedometer is "optimistic" at best. I've done a lot of testing and it appears to be consistently 10% high -- so 44mph reported is 40mph, 66mph reported is 60mph, etc. I'm very used to that.
