The Critical Mass events are held once a month, in a Saturday. A once-a-month event will piss you to the point of violence?

Haven't ridden there in rush hour, so usually there weren't more than a couple other bikes in view. However, I remember ladies riding the bike and protecting themselves from rain with an (opened) umbrella (Netherland is windy, and the wind is not usually steady).
I shudder thinking about biking with an open umbrella, but that seemed so normal to that lady...
Assuming we're talking about twisty and windy road, the driver fell back to have some space to accelerate, and went into opposite lane not because its speed was so great, but fearing of your (not specifically yours, but you know what I mean) tendency to not keep a straight line.
There are conversion kits for bycicles (those contain front wheel or front wheel hub with integrated motor, battery packs, electronics, command and control systems and whatever else), and those can be adapted to any bycicle: http://www.greenspeed.us/bionx_motor_bike_kit.htm First hit in a google link, which conveniently suggests "electric bike conversion kit" when typing "electric bike" in its search box.
As for the higher power electric motors: 250W is enough (unassisted) for a fast walk speed on a 12% hill - but using a bigger motor forces a stronger (heavier) battery and possibly charger. More power than that might be good, though.
As for battery life, ignoring some extra losses due to the bigger and heavier components, if you ride in the same way, the bigger motor would use just a bit more energy (if you accelerate harder with the bigger motor, it will use more energy, though).
If electric cars don't need gears, why would electric bikes? Electric motors have very high low-end torque and quite high max rpm, so they don't need gears.
As for wear on the front fork, guess what happens when someone brakes hard? An even higher effort on the front fork than what an electric motor in traction mode might put, as there is some weight transfer to front wheel when braking.
Assuming that you weigh 100 kg (220 pounds) and climb stairs on 10-feet tall stories, you use 250W to climb a story every 12 seconds.
With a bike, climbing a steep hill (12%) with some 3% rolling resistance, assuming you and your bike are 100 kg total (220 pounds), you can go on electric motor alone at 1.5 m/s (5.4 km/h, 3.3 mph, a fast walk)
by the way, those ~750W were for a mine poney (the first steam power plants were used to supplement coal mine poneys), not for a full horse.
As for climbing a steep hill on a bike at a fast walk speed, let me tell you that it's quite a bit of work, hot and sweaty (I'm talking about kilometer-long climbs)
The "male" models (the diamond frame) is stronger and more rigid for the same mass. On the other side, many MTB frames (even dedicated "male" frames) have a lower horizontal bar (or an oblique top bar)
The ebike thing is perfect when you have some steep hills on the way - instead of chugging along at a walking pace and getting to the top all sweaty, you let the electric motor work, go faster and aren't tired and sweaty at the end.
Also, the assist from the electric motor allows you to go faster and farther, so you're able to use it in more cases than usual. You can also carry more weight (shopping trip) without effort.
There are places where you can drive a low power scooter without a license, but you still have to register it and pay taxes for it.
However, bikes are not registered nor taxed.
Leiden in Netherlands is a great example - even truck drivers on "right of way" roads will sometime yield to bicycles. As a side note, most of the kids come to school on bycicles (in a neighbouring village, 1 mile away though - I don't know about the city center).
This is the level of "friendliness to bycicles" that is necessary for everyone to start thinking about using a bike - when you let your kid go to school on a bike.
They _think_ that the card won't be memory starved at the usual loads. More memory lanes means higher complexity also in assuring the same "distance" (propagation time) for all the memory chips.
People think that the newest AMD card (5970?) is huge, I wonder how big cards with Fermi will be, and how much bigger they should be if needing even more memory chips and memory lanes.
If you can record the RFID code, it's probable that you can videorecord (or record using the eyeballs Mark I) the PIN when entered in some keyboard or another...
The use of a lower quality analog connection leaves you with washed colors and an overall reduction in sharpness. I used one of those (15 feet long), and there is degraded quality from PC to TV.
That's all good and well if you agree with the results of the MetaCritic. However, this might not be the case: as a car-related analogy, while 90% of the people might love black cars, you might hate them.
As a matter of fact, bringing Wii graphical (and compute) power at the level of PS3 and XBox360 would make Wii ports cheaper - one could use the same polygonal models and textures (which one can not do now as it would overpower the Wii graphical engine in geometry and texturing, and probably memory use and so on).
People are used to a kind of look, and won't accept anything less.
I started gaming on the Sinclair Spectrum clones, with their 256 * 170 something displays. I still think those games were looking great, but I hate the look of the flash-based clones with similar resolutions.
People that are used to a level of graphics in games won't accept something lower, even if the play is fun. While Doom could look nice on a phone screen, they look terrible on 19" displays.
So, people don't really want all that realistic look, but they'll downrate the game if it's looking blocky (Doom, X-COM, other old games).
Passcode is not even as secure as the RFID tag - one could usually spy the introduction of the passcode on the keyboard with a camera (if I remember correctly, there were plenty of key-based locks that were visible from the passenger area).
You need sattelite launch infrastructure for that. If you have them, have the satellites in space and can actually maneuver them accordingly, all is fine and good. If you don't have them, if your launch infrastructure is compromised, if the satellites you launched are actually low earth orbit and your targets are medium earth orbit or geostationary, or if your satellites do not have enough fuel to manoeuver against their targets, ground-based lasers (or even air-based) are better.
And with a decreased chance to hit the intended target it the target manage to escape that 10 kilometer wide "kill area" at the first shot. Coming to think about it, if it escapes the target area in the first ball bearing pass, chances are that it won't be on the same path with the ball bearings for a looooong time. So no, I don't think this "space ship loaded with ball bearings" is a good space-based kill weapon.
For your information, 10 million ball bearing having about 5mm diameter would weigh more than 5 metric tons

People like to pick on easy targets - and you on a bike are an easy target to anyone in a car (he can drive away)

But most of us will compare it with the watts needed to run two high end AMD cards
Was renamed GDDR5...
Only joking

Wow... Just wow :|

Iraq should be ready to destroy the US of A if US of A attacked? Panama should be ready to destroy US of A if US of A attacked?
By the way, USSR would have made the rest of communist world a considerable favour if it would have destroyed USA
