Yeh depending on the conditions like all things. I dont speed in public areas, meaning any 60 - 100 areas. But i will put my foot down in areas where there are no houses, no bystanders, & no oncoming cars.
My want to get the spray is simply to help me out if someday i accidentally get caught out or a dodgy speed camera trys to fine me. f#ck that I'll play it safe & get the spray. BTW I’ve never had a speeding or red light fine of any sorts.
