DriveClean - All New Cars in California to get SMOG and Greenhouse Gas Ratings

Monday, July 7th, 2008

Back a half-century ago, Oklahoma Senator Almer Stillwell “Mike” Monroney gave us the ubiquitous window sticker that you’ll see on the side of just about every new vehicle for sale. For your protection, of course. Thanks Mike.

But window space is going to get a little more crowded with information now that California Environmental Protection Agency and the California Air Resources Board have teamed up to give you DriveClean. Now, you’re your going to get a SMOG score plus a Global Warming Score:

SMOG
Smog is a haze-like form of air pollution produced by the photochemical reaction of sunlight with volatile organic compounds (including non-methane organic gases) and oxides of nitrogen that have been released into the atmosphere, especially by automobile operation.

GREENHOUSE GASES
Greenhouse gases (ghg) emitted from vehicles include carbon dioxide (CO2), methane (CH4), nitrous oxide (NO2), and hydroflurocarbons (HFCs) from air conditioner refrigerant. Greenhouse gas emissions are the sum of all the ghg emissions and are identified as the CO2-equivalent value.

So, something like a giant hybrid Lexus LS 600h L, which gets a relatively good Smog Score of 8, will get a poorer Global Warming Score. On the other hand, if they ever tested an old school Honda CRX HF, it would get a very poor Smog Score and a very good Global Warming Score. So it’s educational to have two separate scores.

The all-electric “2008 Tesla Roadster” (both of them! haha!) has a rating of a perfect 10 due to its “0 lbs.” of Annual Smog Emissions. The catch is this: ‘Does not include upstream emissions.” Uh oh. It’s a little funny how some people will bend over backwards to come up with a nonsensical 135 MPG figure for an all-electric car, but other people can’t even hazard a guess as to “upstream emissions,” which exist. (Of course, you power your Tesla with solar, of course, but averaging out emissions from coal fired and nuclear panner plants and the like wouldn’t be a crazy thing to do.)

So, check it out. And don’t miss the acronym page, with plenty of fun phrases like “Partial Zero-Emissions Vehicle.” (How would that compare with something like “Partial Herpes-Free Sex Partner?”).  

During a confusing time when an outfit like Lexus categorizes its hybrid products separately, (as if they’re an entirely different species of vehicle even though they are pretty similar to their gas-only stablemates), these ratings from DriveClean could have merit. So far, so good.

The New Bike Lanes on JFK Drive in Golden Gate Park Need Some Work

Saturday, June 14th, 2008

Here’s the situation. This recent photo shows an interstate bus parked in the westbound bike lane of John F. Kennedy Drive in San Francisco’s Golden Gate Park. Of course the curb is painted red so people shouldn’t park there, but they do. 

So where should a bike rider go? Well, around the bus of course, but that seems a tad on the dangerous side. For some odd reason, somebody decided that JFK should have the widest bike lanes in all of Christendom. And there’s an old tunnel under the road so it has a little kink, as seen here, right in front of the Conservatory of Flowers.

When you’re mapping things out in an ivory tower (ala the abysmal Octavia Boulevard) it’s a little tough to see how things will work out in real life.  

In real life, pugnacious-looking, Norman Maileresque bus drivers will park their 8.5 foot wide rigs wherever the Hell they want.

So, is there another way to handle the striping on this piece of road? Maybe compromise on bike lane width? Maybe take out parking on the eastbound side of the street? Anything?  

Bay to Breakers 2008 - The Truth About Hayes Street Hill

Saturday, May 17th, 2008

Here’s what they want you to believe: the route of the Bay to Breakers footrace is all downhill after topping the Hayes Street Hill. From the website:

ING Bay to Breakers is a 12K (7.46 miles) course. From sea level at the Embarcadero the course rises steeply along Hayes Street Hill. Around the 2.5-mile mark runners climb an 11.15% grade between Fillmore and Steiner, bringing them to the highest point in the race, approximately 215 feet above sea level. The remainder of the course gradually flows downhill alongside the Panhandle and through Golden Gate Park.

But that’s simply not true. Take a look at this elevation profile. See? After dipping down a bit the course continues to rise and reaches its highest point in Golden Gate Park. So there’s a reason why it feels you’re going uphill after conquering the Hayes Street Hill - you are going uphill.

Thousands of runners are in Golden Gate Park today preparing for tomorrow’s race. Going to the west uphill in the Panhandle:

Why does the mainstream media repeat a falsehood year after year? Laziness, mostly.

But check for yourself, if you want. Mike did last year and came to this conclusion:

According to the Garmin GPS I was using, the highest point is indeed in GG Park, not the top of Hayes Street Hill.

So plan your racing strategy accordingly.

Have fun tomorrow!
