Ever More “Speed Hump” Speed Bumps for Golden Gate Park – What’s the Recommended Speed for These Things?

Thursday, November 3rd, 2016

Get up to “speed” here.

Here we go – on JFK looking east towards Transverse / Crossover

And now close to Marx Meadow looking west – this one will be going in soon:

I guess this one will go almost all the way across JFK Drive:

And, now closer to 30th Avenue, looking east – this was the first to be installed, now with a new sign:

I don’t know when I’ll make it back here with a vehicle. IMO, 20 MPH or so is prolly the limit for you. (I had my decidedly non-sporty ride mistakenly set in SPORT mode, but I don’t think it makes much difference on a road regularity as big as this, but I’ll try it again sometime on my ride’s softest suspension setting.)

OTOH, if you have a brand-new BMW M4 GTS, how about 0 MPH as the limit?

And on bikes heading west, IDK. Look out, Jack, is all I can say.

I think the actual speed limit for the bumps is 25 MPH, but that seems too fast for IRL.

Our SFMTA has reported that some drivers go 32-34 MPH on this stretch of JFK and I’m sure these numbers come from someplace real, but I’m also sure whatever stat they’d report has been manipulated for their own purposes, oh well.

On It Goes…

A Brand-New “Near Term Speed Hump” Speed Bump, Installed on JFK Drive in Golden Gate Park

Tuesday, November 1st, 2016

Here it is:

These photos are from a few days back, and this bump / hump itself prolly was installed about ten days back. If you hit this thing at 25 + you will feel it, I promise you. My ride was practically made to handle something like this bump with aplomb, and I certainly felt it. Oh, and look, a speedometer system, of sorts:

Here’s the “near term” language, straight from our incompetent SFMTA.

Humps cause car deceleration without creating the noise, vibration or safety issues associated with their sharper bump cousins.

I’ll tell you, not a whole bunch of drivers go signif more than 25 MPH on the JFK, despite what SFGov might tell you, or imply, with their nonsensical “some traffic travels through JFK at 32-38 MPH type” of stat. Well, sure, some traffic. I go through at exactly 25 which requires a touch of braking on the downhillier parts like near Speedway Meadow. (Hellman Meadow? I don’t think that’ll take for a good long time.) Anyway, if you get on my rear bumper I’ll simply pull over, pretending to get ready to park, and then pull back in after you’ve passed me. But I don’t do that too often.

(If you wanted to decrease illegal “speeding” on JFK, you’d raise the limit to 30 MPH and, conversely, if you wanted to, for some reason, increase illegal speeding on JFK, you’d lower the limit to 20 MPH.)

Anyway, if you want to lower speeds on JFK, you’d put in a brace of speed bumps – that’ll work. Of course, there’d be the noise, vibration, and safety concerns of San Francisco voters, but that will get addressed later, one assumes…

And of course, a few speed bumps is nothing like this recent proposal.

And oh, down Mexico way, if a municipality want to have a nothingburger speed bumps like this, they’d hire somebody to do it one day and then it’d be done the next – it wouldn’t turn into an expensive half-year “project” with countless meetings and endless news releases…

Don’t Dare Park on the Mean Streets of San Francisco Without Your Rubber BumperBully

The owner of this aging, POS, Audi cabriolet sleeps well at night knowing BumperBully Gold Edition is OTJ, I’m sure:

O.K., if it makes you happy…

“The Bumper Bully is the best quality bumper protector in the market. There are lots of cheap imitation products that are PVC based, so there is no rubber in them. The GOLD EDITION is our standard bumper protector. Features Steel Reinforced Straps….NO IMPACT PADS!”

What’s So Great About the Great Sand Wastes? West Bay Trilogy: Virtual “Speed Hump” Speed Bump

Who would do such a thing? DPW or some insular sanctermonious Prius-driving NIMBY-type  living way out in the West Bay?
