If the objective of the fine is to provide a financial disincentive to commit a violation, then the fines should absolutely be scaled for different incomes. Otherwise, there is no real financial disincentive to the rich (who can hire lawyers with chump change), as is obviously demonstrated today. Finally, it is extremely difficult to drive perfectly enough to avoid violating the speeding limit. Signs are often missing or covered. Limits change at unexpected locations, sometimes nasty ones (at the end of descents, etc). There is very little culture of speed change warning (varies state to state, but nowhere like, say, the UK). The poor and the downtrodden have to apply a significantly larger effort to maintain speed limit compliance in their driving, because the downsides of getting a speeding ticket are so financially devastating.
