So wait….


….there were no skid marks at all?….not even rubber on the ground from your wife's car (…e.g. a strip, or strips of rubber left on the ground from her depressing the brakes when the impact occurred)? All you need are a few values to start working through the calculation. If the car has an EDR, you'll get speed values pre-crash, brake info, etc. There are also published co-efficient rates for all surfaces (…e.g…asphalt, cement, grass, sand, etc.) or you can use a drag sled to obtain those figures; all decimal. I can go on, but you can calculate it all.
Well maybe I'm wrong. They said there were no skid marks indicating the girl ever touched her brakes. Perhaps there were marks from my wife's car. Hadn't thought of that.
If she were stopped and on the brakes, her tires would definitely leave marks if impacted at 60 mph. I'm glad your wife was okay. That was a significant collision.

Even with ABS? Does it leave dotted/hopping skidmarks that there's a formula for?

In case it's not clear, I'm asking about skidmarks on the pavement...and not the driver's underwear/seat.....

You've got jokes this early in the morning.

ABS wouldn't be a factor since she is stationary with the brakes depressed. A collision like what you described wouldn't activate ABS. A collision while stationary leaves a dark scrub mark.

It's after 9 AM on this coast.

I was thinking of the moving car's skidmarks, not the stopped car. For sure the stopped car would not go into ABS mode as long as the driver held the pedal firmly, and is probably a better measure of the moving vehicle's speed when you model a totally elastic collision between two known masses.....

Generally speaking, the car that is moving and collides into another object/motor vehicle - without ever applying the brakes - won't leave skid marks. The Crush Formula (CF) is used to determine approximate speed(s) in a situation like the accident you've described.

Some of the experts in the field who teach accident reconstruction have run tests where they have driven cars into other motor vehicles, poles, brick walls, etc. One of the lead guys on this coast has been in over 3000 test accidents.

Thanks. Sort of OK. This was years ago and her back has never been the same. Looking like surgery this year if any surgeons think they can help.

When she had the wreck I was 3 miles away eating lunch after golf with a friend. A good Samaritan used her phone to call me and I was there when the ambulance arrived. Scared me to death seeing them put her on a backboard. One funny aspect of the story is to this day she doesn't believe me that I was there. Total blank for that period.

QaShontae Hosomla Short-Brundidge, ie. Karen, sues Richard Jordan for a bad date. And she wants him to pay $10,000.00 for perjury. Check is in the mail.

That woman is both unstable and stupid. The fact it was one date and done is because she is mental. My guess is when he met her and realized how far gone she was he never called again and that set her off.

Would be something to be in the courtroom when the judge throws her case out; and possibly her in jail. Guy has good instincts.

I was shocked by how tolerant he was of her. She continued to show him no respect at all. I also wonder if the guy being sued could have verbally requested dismissal and judge was waiting for that. he should have asked what the process was.

But pretty sure it's over. When she realizes she got dinged for court costs and the case will die until she pays them I'm guessing she'll go into a rage. If I was the guy I'd watch my 6,

FYI, the Manhattan DA has decided to dismiss the murder charge against the bodega worker who stabbed an attacker.

FYI2, Rochester PD has now suspended the police investigator who handcuffed a working EMT at the hospital, while she was unloading a patient from her ambulance for emergency treatment. She allegedly bumped his patrol car when opening the ambulance's door at the dedicated ambulance unloading area, where the patrol car probably never should have been parked in the first place.....

The D.A. got that one right, although charges should've never been brought in the first place.

It was disconnected. We performed ABS skids using the BMW R1200 motorcycle.

I wish. Lol! The big wigs in the industry do though. My department, LAPD and a department in Michigan do fleet testing for the entire country. The figures we publish are what everybody else utilizes.
