If you find yourself sitting in cars now and then, this might be interesting to you and help you prevent accidents.
So if you open a cars door from the inside, you open the door with the hand that's not next to the door. This means that you turn around you body which automatically turns your vision in the direction where other cars or bikes might come from.

I was taught this early on I believe, anyways this is the way I have always done it.

@pinkprius Don't have to watch for bikes if you park in the bike lane :smart:

@pinkprius If you pay attention to using your other hand, you can also pay attention to simply TAKE A LOOK AT THE MIRROR AND BLIND SPOT. If you don't care about possible incoming bikes, you won't care to use whatever technique someone told you could save lives.

As with many other things on the road the main part is giving a fuck about other road users.

@jkb the strength of this technique is that you do it without thinking about it.

@pinkprius I check my mirrors before opening my driver side door when I'm parking in the front lane of my house where there's no possibility of incoming traffic, do you think I do it on purpose or do I do it because I've forced myself to check my mirror so many times it's become second nature?

@jkb @pinkprius

here in Britain it is drummed into your head during driving lessons to always check your side mirrors and blind spot for cyclists - I only passed my test last month so it is still fresh in my mind but because I am also a cyclist and only got a car late in life its not something I am as likely to forget.

Over here its common for cyclists (even grown adults) to ride on the pavement (sidewalk) not because they want to be bad/antisocial but they feel intimidated off the roads..

@pinkprius @jkb Except for the extraordinary twist in the spine. I prefer the 'check the mirrors' option. Also the original document needs to be available for RH drive cars.

@jkb If you set up your mirrors right, you don't have a blind spot. Dutch Reach is still a good idea, though, if only because it really helps getting on your feet quickly from something lower than a truck.

@BalooUriza @jkb

The strength of this technique is that it works for any seat of the car. Children could do it as well.

@pinkprius @BalooUriza @jkb yeah, that seems very useful in towns with bike lanes on the pavement as well

@jellypotato Ideally the bike lanes are protected, so, this is more for general traffic and on street door lanes more than anything.

@pinkprius @BalooUriza @jkb @jellypotato

on many cars side mirror curvature is different between left and right (depending what side of the road you drive on) to try and eliminate blind spots, but over here its common for drivers to leave a view of the kerb in the mirror on the opposite side to make parking easier (so you don't park too wide, nor scrape your wheels against the kerb)

Dutch reach definitely makes sense for passengers as they are equally/more likely to open a door w/o looking >>

@pinkprius @BalooUriza @jkb @jellypotato

Very few drivers *want* to risk a collision of any sort, even a low speed one where no one is hurt as the door is almost certain to be dented and paintwork scraped.

That costs money to fix..

@vfrmedia Door collisions are the highest cause of injury for cyclists riding legally. The highest cause of injury and death overall is riding on the sidewalks tied with riding against traffic.

@vfrmedia You can set your mirrors to SAE recommendations and still see the curb. Tilt the mirror down more. Sky doesn't need to be half your mirror's view.

@BalooUriza to be fair this is exactly what we are taught at drivers education over here (which is of a very high standard, the UK's roads are some of the worlds safest) - the problem is people seemingly forget the lot once they pass their test - or simply lack the empathy for other road users (psychological assessments are only a thing for bus and large vehicle drivers)

That's not true. Your rear view mirrors have a small viewing angle, and are optimised for looking back. Your blind spot is right next to you. If you have a blind spot mirror, the viewing angle is even smaller.

@frank87 maybe if you have your mirrors turned in to look at your doors. Try moving them further out, then the end of your mirror should just barely cover the periphery of what you can see looking to the side to about what your center rear view sees.

@BalooUriza @frank87 I've tried this setup yesterday and it *almost* works as my center mirror doesn't have a wide enough angle to cover everything the side mirrors don't. Maybe european regulations regarding mirrors are different from the ones in the US. Anyway, I'll still peek over my shoulder before every turn or lane change, it may be useless most of the time but it will prevent a sideswipe someday.

@jkb @frank87 Unless you have unusually large mirrors, you still have to move your head a bit to get everything in the mirrors, but having a gap you can see in your mirrors is a lot better than having a gap at an awkward angle you can't see without performing contortions.

@jkb @frank87 But, even then, setting your side mirrors so you can only barely see the edge of your car in them if you don't have a center mirror (or you're driving a truck) is still better than thinking you're going to see (or even want to see) straight back in the mirror. Even backing in trucks, this provides better backing visibility than centering the mirror on what's directly behind you.

You should see the side of your car, for manoeuvres, especially parking. But it's lost viewing angle, so it should be as little as possible.

@frank87 Exactly. But I can lean my head a little closer to the side I'm trying to see if I need closer in. That's easier to do in a low speed and infrequently performed maneuver compared to driving forward in city traffic or on the highway.

@pinkprius I've been taught to treat it like a lane change or any other maneouver like that:
Rear view mirror, Side mirror, check your blind spot, then exit.
@pinkprius This is really good info! noone ever taught me this, I'm going to work to do this :)

That's good to hear, it's really easy, I don't even think about it

@pinkprius How have I never been taught this before, I always get massive anxiety opening my driver's side door into the roadway because I fear I'll open my door right as someone's passing by, either another car or a cyclist

@Frinkeldoodle same. It is dangerous to leave a car, especially on the road side, but on the other side as well, if there are bikes going past.

@pinkprius OR you could look in the mirror that's mounted to the door for exactly this purpose! It's actually dead center in the view field on your "don't" picture.

@pinkprius as soneone who has been doored before, and pretty seriously, I second this.
