Move it!

All would be great if they moved the transfer station. What a crappy deal, you have to sit out there and wait half on and half off the road untill they change the container. You can go around people, illeagally. It seems they come change it when most peeps want to stop by there. I am thinking about just stopping my truck right in the middle of the road since there is not really a place to pull off. It will take a few more terrible wrecks before they move it. Ask Jerry Clark about it and he will say something needs to be done. I guess he is waiting for someone else to do it.

That speaks to either a following distance that was too close, .

Best I can find, so far, is that, in general, a bike CAN stop in 15 feet at 20 mph and a car CAN do it in 20 feet. Both distances increase when adding reaction time but, in general, the bike is going to be ABLE to stop in less distance.

Riders know, anyone who took the MSF, that you have to stop in 23 feet (or less) at 20 mph to pass. I can't see a car doing that, not even in the MSF conditions; here's the test, here's what you need to do.

However, I have heard it said that bikes stop hard, faster. Cars stop hard easier. Point being it comes down to skill, many of us do not stop hard well.

I try to keep a distance, car or bike, and this is what I've taught the kids as well, that leaves me what I think and feel is enough room to stop if the car in front of me suddenly slams 'em on, reaction time and stopping distance, including speed and conditions, and that when I am too close to do that, it's on me if something goes awry.

So far, the riders I know who have run into the person in front of me all admit, sometimes after a bit of cajoling, that it was their fault and not what they ran into.

I know this much; I worry a hell of a lot more about being run into in an emergency stop than me running into something in front of me and I try to add even more separation to allow for the vehicle behind me.

why so serious
Rider is a coworker of mine. He's still in the hospital but recovering. Ea an experienced rider that was unable to avoid the emergency stop that occurrd in front of him. He will make a full recovery.

I'm happy to hear he's recovering, thanks for the update on his condition. :buddies:

Basic physics :shrug: mass and inertia it takes a lot less friction to stop 700 lbs of motorcycle than 4000 lobs of car.


I've found that weaving back and forth in your lane will usually cause a car to increase their following distance.

dont forget the tread touching the ground and the weight per square inch that is exerted on that tread. Just another part of that equation.

And how fat or skinny the rider is. Changes the inertia quotient lots....

road conditions, road type, tire type etc...
many factors involved in figuring out exactly how long it will take to stop.

bike tires have higher friction quotients than most car tires

Hopefully you won't have a 500 lb babe on the back

doesn't apply, both vehicles would be on the same surface

What part of "basic" was confusing? :buddies:

Don't forget, braking systems on both work by converting kinetic energy to heat energy and dispersing the heat. Friction and adhesion to the road surface only come into play if the energy conversion of your braking system is converting the energy to heat more rapidly than the system can handle (disperse to the atmosphere) and the brakes lock, or if you are running on cheap or bald tires, or crappy weather conditions, which break adhesion prior to heat induced brake lock. Avoid the skid and you avoid the tires doing the job rather tahn the braking system, and stop quicker.

Simple physics. :yay:

I do that all the time! To be seen, to practice turn initiation bith ways and, well, because it's fun!!! I'm like a little kid on a bike; pure joy.

Same here Larry. And Aps, even if my bikes tires are twice as sticky as my car tires, theres no way in heck hey have more total friction with the road. My cars tires are almost 11 inches wide, and say 3-4 inches front to back in contact with the surface. Thats about 132 inches of rubber in contact. My bike, I would say cannot have more than 2 inches wide and 3 long, for about 12 inches.

As for the simple physics, there is swept area of the brakes to consider. I will concede that most bikes outbrake most cars, given operators of similar experience, but its not always the case.

Looking around, seems bikes are about even with the best cars, in braking. But, I think when you test the average rider, the skill required to brake that bike to that level is lacking. Whereas its much easier to brake a car at max.

That is the key. :buddies:

Arguing road contact and rubber on the road is like arguing an 18 wheeler is going to be able to stop sooner because it has more rubber on the road.

There is no excuse for a bike running into the back of a car; rider error.

And it depends on the bike/engineering.

100% full braking both front and rear available with just a little pressure from a single finger on the brake lever. Coupled with ABS takes the guesswork out of braking when it matters most.

My car has that, sorta scary when described, but in practice, they found that in emergency braking, folks would make an initial stab at %100, but almost immediately back off. Its called the BAS. Uses pressurized fluid in an accumulator to maintain %100 braking.
