Speed limits on freeway

Accident in the sense that most of them are not intentional which is the opposite. The event can vary, but nobody intends to have one of them, thus accident is appropriate. It is also the common use.

I have one of those gethomeitis and do what the FAA expects pilot stories. IFR from Cape Cod to Frederick MD in the days when low cost Nexrad was just becoming available in the cockpit. About a 3 hour flight. Filed and was cleared down over JFK, NJ and DE coast, then right turn and on over BWI west toward central md. As we passed into MD we went into solid IMC (instrument meteorological conditions). The area forecast had warned of embedded tstorms so I asked ATC if they were painting any weather. They said no, and no pireps (pilot reports). So on we went Got set up on the approach and ran straight into a level 3 cell. Lost radio contact and didn't want to screw up all the traffic in the busy airspace so I continued the approach, after tightening our seatbelts cause we were banging our heads against the ceiling. Had to hand fly the approach, autopilot wouldn't stay on.

Got on the ground in pouring rain but just rain, we'd passed through the cell. Just sat in the plane for a half hour. Wife said she'd never seen me hand fly an approach that well, indicator needles centered the whole time. When we finally got out the paint was gone off the leading edges of the wings and tail. No hail damage, just from the rain.

Turns out ATC's radars at that time were 20 plus years old and didn't show much weather detail. And ATC has no obligation to report weather anyhow, their responsibility is traffic separation. So I ordered Garmin's satellite Nexrad the next day and that was the last time I ever flew into clouds when embedded tstorms were forecast. The airplane needed new paint anyway...

I've heard that one. 

We tow a 179 with a Lexus GX470 - as far as I know,  pretty much the same V8 and tranny as your rig. You're from the west so you know about mountain driving. We live in Colorado. I would say we average 60. On long, straight stretches (think utah and wyoming) closer to 65 cruising, but try not to go above that. Take our time on hills. If its windy, especially if a headwind,  we notch it down. With a good WDH and  sway control, its pretty darn stable. Really important to keep your speed under control going downhill - make  sure that your brake controller is properly adjusted so that your vehicle brakes arent doing all of the work.

The official aviation term is "continuation bias", a form of cognitive bias to continue with the plan despite changing conditions. It is quite hard for type A personalities to overcome, they have learned to have life success by by being aggressive and willful. As most pilots are in this category (or they wouldn't be able to either afford an airplane or the training, often military) continuation bias is at least a partial cause of the majority of aviation accidents. In my personal flying experience I know its hard to overcome, especially flying IFR where air traffic control expects you to follow the clearance you've been given all the way to the destination and you have to request and be approved for any changes. Now you have both your own gethomeitis and the federal government's (FAA's) dowhatyou'resposedtodoitis to overcome.
