Unless you scale fines with income/wealth, fines are just a way of letting the rich do what they please. On the off chance they're caught - and don't get let off the hook because of how 'respectable' they are - it's so little money to them, it's not a discouragement at all.
A fine for dangerous driving that is crushing to a day laborer is unnoticeable to someone wealthy. And whereas that laborer, to challenge a ticket, would need to take time off from work costing them further - the wealthy person may have a standing relationship with a law firm, and that law firm might send a clerk or paralegal to challenge the ticket in court...and do so gratis.
