[Triple Word Score]

Yeah, but can the guy behind you and in the lane next to you handle 85 mph, and is everybody's car well-maintained? Is there metal fatigue in your axle, are your brake pads working their way loose? Is everybody on the road sober? Are all loads secured? Is some old lady on the other side of the interstate about to find out that the pain in her chest and arm WAS something to worry about? You can handle 85 mph--can you handle 170? She's coming across the median now, unconscious at the wheel....

I believe you changed the criteria. As for your cases, 45 pretty much fails those tests.
