Segway Banned In San Francisco
bhsurfer writes "The city of San Francisco has banned the Segway [CNN.com] from it's sidewalks before they've even arrived. Apparently Santa Cruz, Oakland and San Mateo are considering a ban as well. What a bunch of spoilsports...or are they? Any thoughts on this?" According to the article, hiring high-powered lobbyists may have backfired. but the city claims safety concerns are behind the decision.
Segway, cool toy, but I just don't see what I would do with it. I can already go on my skateboard pretty damn fast. If I need to go faster I have a bike. If faster than that, my truck. Otherwise I'm walking. I don't get where it fits in, other than some lazy asses and maybe a heavy duty one for delivering mail along the boardwalk.
I'm not even sure that my kid thinks they're cool. I'll ask when I get home.
The first (in fact only) time I've ever seen a Segway was on the streets of San Francisco. I saw a Postal employee riding down the sidewalk with his USPS-branded saddlebags on the sides. I wonder if they have had bad experiences with Segway on their streets...
youre not supposed to ride bikes on sidewalks! youre supposed to ride them in the street!
as for the segway, i think they should wait for it to be a problem before wasting their time banning it....i mean, how many of these things did they anticipate being on the sidewalks anyway?
Gentlemen...BEHOLD!

The ones being sold to the public have an 8 mph limiting key. The industrial ones had a top speed of 15 mph but aren't meant for streets. The skate boarders and bicycles go faster than that on sidewalks. The are a potential hazard but so are many legal devices.
The Segway might be safer for the rider than a skateboard et. al., but it sure as shit isn't safer for the other people on the sidewalk. It's an extra 70lbs -- on top of who knows how much tofu- and sprout-fed mealy Californian -- moving at up to 15mph. Given how godawfully bad San Francisco drivers are, I shudder to think how many pedestrians would get plowed over by yuppie asshats with their new $8,000 toy.
I have no problem with keeping these things off our sidewalks, for the same reasons that I have no problem with bicycles being confined to the street.

To spur "enterprise Linux," Big Bang, the distributed two-phase commit.
Bill Gates weighs 70 pounds and only goes 10 mph, and just look at all the damage he has caused!
In California, officials in Santa Cruz, Oakland and San Mateo are still waiting on additional payoffs, and are wary after the much publicized "payoff check is in the mail" campaign failed in San Francisco.
One official is quoted as saying, "Bring cash."

Yes, San Francisco banned this device. We have some very liberal board of supervisors running the city government here that defined the word 'bleeding heart.' Granted, some of the reasons for the ban aren't too bad, but some of them are very big brother.
The problem is that everyone is worried that the elderly walking down the sidewalk would be injured by one of these things.
There is also the whole pro-walking thing which lobbied pretty hard against it. They believe this device would cause everyone to get fat.
The price of the device didn't help its case either. Being a liberal city, a $4000 device is seen as a rich man's toy and rich men should be spending their money on social problems such as the homeless problem, not toys. This viewpoint is pretty common here unfortunately.
Bikes have been banned for quite some time on the sidewalk and for anyone who has biked down Market St. knows, it isn't particularly safe to be in the road either.
Rollerblades have also been banned on the sidewalk for some time. I've seen people try to go down the road on them and it isn't pretty given the general quality of the roads themselves.
Powered scooters are getting more and more common. They seem the safest of any one-person mode of transport simply because they can keep up with traffic. They are obviously banned on sidewalks, but have no real problems with the street from what I've seen.
Powered wheelchairs however have not been banned even though they seem to cause a whole lot more injury than anything else. That would hurt the disabled however, so it isn't even considered.
On the other hand, you have to realize that the sidewalks are litterly *packed* with people in many parts of the city. The segway would have caused problems simply because it is impossible to walk without bumping into someone.
The world is neither black nor white nor good nor evil, only many shades of CowboyNeal.
youre not supposed to ride bikes on sidewalks!
When I ride my bike in a downtown area where there are lots of cars parked on the side of the street, I get on the sidewalk and ride slowly.
The reason is that I can't rely on the drivers watching before they slam open a car door. Technically I'm not supposed to do it but I've had conversations with cops about it and they mostly agree that I'm better off on the sidewalk as long as I'm going slow. Same will probably be true for segway.

And give you a hefty $70 fine. Bikes are treated as motorcycles from a law enforcment standpoint. They must abide by all the same laws. No sidewalks, no running red lights, must use turn signals etc. The reason you see so many people ON sidewalks with bikes is because police are typically lax on chasing them down in a lot of areas. But in high pedestrian traffic areas you will see lots of "bike cops" making sure bikers are on the road where they belong.
Human powered top speed: 80.6 mph
and after some quick calculations
60/((9.7*16)/60)
Human top speed on foot: 23 mph
12.5 mph doesn't seem so dangerous to me, it is about 3 times faster than I walk comfortably, and slightly faster than when i jog.
Really? I've lived there 10 years, 1/2 mile from Waikiki, and I've never seen mopeds on the sidewalks *everywhere*. I do ocassionally see groups of tourists with mopeds *on the road*. But I see more mopeds on the University of Hawaii campus than anywhere else. Not on sidewalks either.
Saw a Segway friday evening in Portland OR.
The operator was driving down the street at night.
No lights. No reflectors. Grey vehicle out in traffic and no helmet on operator.
I'd ban the damned things too.
The title should include the word "sidewalk" in it. Many posters think that the devices have been banned entirely.
Lets apply the conservation of momentum to a situation involving a man walking toward another man of same mass going 15 mph on a segway (for this we'll neglect friction).
Vi1 = 2.235 m/s (5 mph)
M1 = 77.27 Kg (150 lbs)
Vi2 = 6.705 m/s (15 mph)
M2 = 100 Kg (220 lbs)
say at the end the segway with rider stops in its tracks and the man goes flying, and since the man is travelling toward the man we can say he's going -2.235 m/s.
Pi = Pf
M1(Vi1) + M2(Vi2) = M1(Vf1) + M2(Vf2)
(77.27 Kg)(-2.235 m/s) + (100 Kg)(6.705 m/s) = (77.27 Kg)(Vf1) + 0
Vf1 = 9.648 m/s or 21.583 mph.
ouch.
(sorry about repost forgot to put in my pw.)
I've seen two yuppies (the financial kind) whiz by on the sidewalk in front of my office in downtown San Francisco (so much for "a device that hasn't arrived yet"), and I wholly agree with the ban - these contraptions are a serious hazard to pedestrians. They are wide, have a high center of gravity and are very fast. They will also probably be driven by the same heedless people who burn red lights in their SUVs (I see that happen at least twice a week in SF).
