Nope most speedo's are 5-10% optimistic. You can tell this by when you go on the highway and the radar sign says your going 67 when your speedo reads ~75. This isn't even factoring things like tire circumference which can be effected something as simple as tire pressure
If you want the most accurate reading, either GPS...... or the man with the radar gun
