that's why tickets are seldom given for that small an amount above the
speed limit.

talking to a local radar trap cop ....he told me they give a ticket at 9

that means you can go 43 in a 35 and won't get busted.  A reasonable
margin.

'my speedometer reads low' would be a really thin defense anyway.
