Ask horn671 he’s the expert. I concurred with him after going to encarta. I think it has to do with heavy crude.

At least you admit you have no clue. His shoes don't have clips on them. Plain tennies.. You couldn't see that?
I noticed that too. If Biden was wearing clips, they are of a type I have never, ever seen before.
Bubba,
Another reasons Biden almost certainly had no clips.
You wear clips to improve speed and/or endurance via improved energy transfer between your legs and the bicycle. On a standard bicycle with pedals, you transfer energy solely by pushing down on the pedal, left leg, right leg, left leg. You get nothing on the upstroke. On a bicycle with cleats and clips, your foot is in a shoe that is attached at the ball of your foot to the bicycle and will not come loose until you make a specific movement that releases the clip from the cleat. My clips require me to move my heel outward/toes inward to release the shoe. This attachment allows the cyclist to take advantage of using both the downstroke and upstroke of the legs to propel the bicycle. It is not a set-up meant for 79 year old, half senile men who are out for a casual photo op ride.
You can certainly tell a specialty cycling shoe with clips from a regular old tennis shoe.

Upon further review of the video, Biden had toe cages. Much easier to get your foot out of, but much worse in terms of energy transfer. Whoever put him on a bike with toe cages should be fired on the spot.

I was offering up what the left wing twitterverse was saying. That’s all.Bubba,

In this circumstance, the twittiot you linked was correct about the equipment in use.

I haven't ridden since 2004 (too dangerous in dfw) , but your cleats look a lot better than my old ones. I had Time shoes and pedals. Those cleats were beefy, but easy to get off the bike
Put more bluntly, he is seeking to buy votes for less than $50 per vehicle given the presumption of the average driver filling up once a week across the next three months.
He has ZERO reply for how the gap in highway infrastructure funds will be filled which come directly FROM the federal gas taxes.
Your gas will be $0.12 per gallon cheaper, for which you will suffer with roads so full of unrepaired potholes, your vehicle will inevitably need a new suspension at a nice $2k price point.
Joe does not have a single clue.
I think the real goal of dropping the tax and getting some states to do the same is to avoid the next three months of this headline.....
"Gas hit an ALL TIME high at the pump AGAIN this week"
Imagine that headline every other week throughout the summer. The Dem's and Brandon would drop another 4-5pts in the general Rep/Dem matchup. It's all about the optics.
McHammer tainted my post?
No, the US consumes roughly 20MMbpd of oil. In late 2019, we peaked at 13MMbpd of production. Furthermore, we export a lot of our crude because most of our refineries were not designed for the light crudes that comes from most US shale reservoirs.
Short-Term Energy Outlook - U.S. Energy Information Administration (EIA)
Correct on the first part. According to the EIA graph, we are currently exporting more than we import.
Never mind - I realize that I don't understand their graph.

OK, ChE. Without going into a graduate level lecture, can you please tell me the differences between light crude and heavy crude? Sour and sweet? And why do these differences make it more economically feasible to export light crude rather than retooling or adding on to our existing refineries to process it?
And FYI, I do have enough of a chemistry background (Chem minor at UT) to digest moderately technical explanations.
I actually work in Upstream but understand enough about Downstream to be dangerous. Light and heavy refer to the density or API of the crude (light is low density, heavy is high density). From a high level, heavier crudes have higher molecular weight, low volatility components that end in bottom of the crude unit, vacuum distillation, etc. The lighter crudes have a large percentage of lighter components that end up choking the overhead of the crude unit. If your plant is not designed for the lighter crudes, you will hit a plant "bottleneck" or limit quicker and therefore make less liquids.
Sour just refers to sulfur content. Most refineries use hydrotreaters to convert organic sulfur components to H2S (which is removed using amines and Claus process). This allows for high sulfur crudes to be meet tight sulfur specs while increasing liquid yields.
So different types of crudes have different blends of molecules that go to different parts of the plant. That's an over-simplistic explanation but you get the point.
I'm getting the idea that treating different classes of crude requires a lot more than retooling one production line at a refinery.
Still, seems to me we should have a more robust refinery capacity in the USA to handle the primary type of crude produced here.
EDIT: Thank you for taking the time to provide the explanation.
