comment Is my stopping dangerous when Idaho Stop is de facto but not legal?
Hand signals are frequently used by road cyclists when riding in groups, to signal to the other riders with them. Turning or stopping without indication when you're riding with 5–100 other people is a fantastic way to wind up with road rash. For typical commuting, where speeds are slower and other cyclists aren't as closely bunched, it's not as big a deal — and I doubt anyone anywhere is actively ticketing cyclists for failing to use proper hand signals. That said, simple "I'm going over here" pointing hand signals are useful when you're changing lanes or at intersections with other traffic.

Only when riding with other cyclists, or signaling an "unexpected" stop (e.g., not at a stop sign or light). I also don't use the "official" right-hand turn signal (I simply point where I'm going). The hand signals were designed for drivers of cars prior to the existence of brake lights and blinking turn signals — they make no sense for a cyclist. Worse is that nobody but cyclists have any idea what they mean. Everyone understands pointing in a direction.

To OP, yes, you can get a ticket. But the odds of getting a ticket are vanishingly thin. That said, you should ride in whatever manner makes you safest. I tend to go with the Idaho Stop, because I believe it isn't inherently any less safe (especially when other cyclists who may be behind you expect you to behave similarly). That said, I will always let a car go if they have the right of way (not to mention if they don't, if it looks like they'll go anyway).

@Frisbee I live in SF. The Idaho Stop is de facto in full force.

comment Are MIPS helmets actually any safer than standard helmets? Independent Research?
It looks like the point of contention is whether or not the helmet actually reduces the types of injuries associated with oblique impact.

comment How much faster will I be if I lose 10kg (from 100kg, all else equal)
Actually, losing weight has a harmful effect when it comes to air resistance. You have less momentum, so are slowed down more by onrushing air.

I've actually bought a compact crankset a few days ago for exactly this reason. Thanks!

comment One Month to Build Endurance
I want to complete these climbs at as fast a speed as I am capable, seven days back to back to back. I'll be with other riders, but outside of competitive spirit, the climbs will be at each rider's individual pace. We regroup at the summit of each climb.

comment I don't want to be the next Eddy Merckx; Is competitive cycling right for me?
The answer to that is, really, "be sociable". Meet people. Did you like them? See them again. :P No sport has a monopoly on a supportive community, nor are the communities surrounding a given sport the same between towns, states, regions, or countries. Go do things you think are or might be fun. If you meet cool people, great.

comment Validity of UCI motor concerns
Even the smaller one (at 110Wh for 4lb) would be an incredible help. Two hours of an additional 50W (around 27W/kg, compared to an elite rider who can sustain less than 7W/kg for long climbs) could easily be the difference between a pack finish and winning a race.

comment Validity of UCI motor concerns
A weight test wouldn't suffice. Bikes already frequently weigh less than UCI regulations, but weights are dropped into the seat tube to meet the minimum. Per the article linked by @altomnr, a motor and battery capable of delivering 165Wh of energy can be had for under 5lb. The UCI limit is 15lb, but carbon fiber racing bikes weighing under 10lb can be bought today. A rider could easily use the motor just for climbs (offsetting its weight), and disable it on the flats where the extra weight is of no consequence.

comment Do certain makes/models/types of bikes get stolen more than others?
The most commonly-stolen type of bike is an unlocked one, followed closely by one locked with a cable.

Also, working up to longer distances will quickly let you know if you have a fit issue on your bike.
