If you appeared before magistrates in 2004 you had a 4% chance of getting jailed per court appearance (more, if you done it.) Summary motoring offences make up 50% of total court proceedings in the UK. The average magistrate is 57 years old and sent six and half people to jail last year. 93.3% of magistrates are white.
Nothing wrong with that, of course. Many of my best friends are whites.
