She was wearing a helmet and she left a nice dent in the side of the car. She came out of it stunned but alright. I doubt she would have had the same outcome had she not worn a helmet.
I don't think I have an anti-bike bias - I don't own one now, but I rode for years and the only motor vehicle I've owned was a motorcycle; I don't like driving a car unless I have to.
Was the student going down a hill? I'd have to be facing some major deadline to be going 25mph on a bike on a straightaway.
Unless it was seriously down hill or with a serious tail wind, and she was extremely lucky, I bet she wasn't doing 25-30 mph.
I think that bet is safe because the world one hour record for women is about http://en.m.wikipedia.org/wiki/Hour_record#One_Hour_records_... 29 mph.
Also, a bicycle helmet doesn't do much good in a head-on impact at 25 mph. It only gives you a few mm of deceleration distance. So, if the impact was at 25mph, that dent in the car likely did way more for her than her helmet.
But it's not a tradeoff. Cycling rates have skyrocketed over the last 5 years in SF and NYC, without any real change in attitude towards helmets. We can thank bike lanes.
The car analogy doesn't hold water either--the most effective safety device for cars is the seat belt. Nobody thinks seat belt use is a sign of a risk-obsessed driver, and likewise, wearing a helmet doesn't mean you treat biking as a risky behavior. In both cases they're just sensible precautions for a common activity.
Where I am, there are more things than cars that will take me out, and a helmet is one thing that protects me.
Low hanging or falling branches, massive potholes that can kill your tires and bike wheel, people carrying large objects out of the trunk of their car - so even if they are driving safely, it only takes one snapped bungie cord to have a piece of furniture come at you...
Always wear a helmet regardless of how safe you think cars are being!
Same rule applies for driving, walking, and basically everything.
According to http://www.bicycling.com/news/advocacy/ride-smart almost half of car-bike accidents are due to cars turning left, and NOT seeing the cyclist.
There are many, many places where the option to ride without a helmet does wonders for cycling culture.
I'm genuinely interested in the benefits of forgoing safety equipment that is readily available, easy to use, and proven to save lives.
Perhaps my experience is skewed because I almost exclusively do mountain biking. You couldn't pay me enough to ride on urban streets contending with cars.
There are several videos of cycling in the Netherlands on YouTube. Most of them have been speeded up because they look so slow.
Helmets are pretty universally known to reduce traumatic brain injuries.
Elvik writes "When the risk of injury to head, face or neck is viewed as a whole, bicycle helmets do provide a small protective effect. This effect is evident only in older studies. New studies, summarised by a random-effects model of analysis, indicate no net protective effect".
I'm guessing you didn't read it and assumed it supported your preconceptions?
I specifically mentioned head injuries (TBIs) - there are two meta analyses listed, the point you listed went beyond that (to include neck and face injuries). The other meta analysis also supported its TBI-reducing benefits.
Edit: If you're looking for the pertinent line from the analysis:
"With respect to head injury, the answer is clearly yes, and the re-analysis of the meta-analysis reported by Attewell et al. (2001) in this paper has not changed this answer."
What you actually said was, "Helmets are pretty universally known to reduce traumatic brain injuries."
This is wrong and not what you are now saying. You are now saying that among people who have suffered brain injuries, helmets are known to reduce traumatic brain injuries.
If the helmets make it more likely that you suffer an injury in the first place, it's not really a consolation that they mitigate the effects. There are actually reasons why many people oppose compulsory helmet laws.
If both cyclists and other traffic behave normally wearing a helmet whilst cycling is as idiotic as wearing a bullet proof vest while walking.
Not everyone lives in the US where the cycling culture is a mix between cyclists racing through traffic where the drivers can legally get away with murder.
I use EAGLE to make the breadbord, Proteus for simulation, and NI Multisim to produce the schematic to print on paper (they look nicer than Proteus' or EAGLE's schematics).
I also use LT Spice for simulation. It depends.
Did anyone really have a problem with directions when biking? I mean the great thing about a bike is that it's pretty easy to come to a stop and grab your phone if you get lost.
I've never had a problem finding my bike, even amongst a rack of hundreds. Getting the bike out... now that's a problem worth solving!
And connected biking? Wtf? Nearby friends? If I'm out on a ride and one of my friends is nearby, but I'm not biking with them, why the fuck do I care? Am I going to stop my ride to pull them over and say hello?
How do I prevent it from getting stolen?
Built into handlebars seems limiting, and error prone--what happens when you're wearing gloves, or braking
