Confused
Don't worry but I think somebody got confused while usign LHD and RHD back and forth beetwen different countries, so for example, Spain is LHD or RHD? the part about Gibraltar made me get confused about it.  —Preceding unsigned comment added by 98.226.204.140   

Gibraltar has not been part of Spain since 1713, so the British authorities applied their own laws, including the rule of the road. By 1929, driving on on the left while having a land border with a country that drove on the right became impractical, so that's why Gibraltar change on 16 June of that year.  

History
Do we have any reliable evidence about the historic foundations of LHD/RHD are? I think the article could benefit from adding any info to this effect.
On numerous occasions, I have heard that left hand driving has its roots in knights passing each other with the lances in their right hand. However, i have never been able to find any evidence of this. 
  

-Please do excuse me for sounding a bit daft, but I'm not sure I understand the question. Isn't that what the entire article is about? In addition, I think the problems ascertaining the specific history are quite well-presented.   

Sweden
Under Safety factors it says
""Research in 1969 by J. J. Leeming showed countries driving on the left have a lower collision rate than countries driving on the right. This research is questioned in Peter Kincaid's book on the rule of the road,[citation needed] but some countries that have switched to driving on the right, such as Sweden, have seen their long-term accident rates increase by more than any increase in traffic volume[citation needed]."" The red part is totally made up, and the opposite is the truth. The number of accidents was cut in half from the first day of right hand driving, and has not increased substantually since then. Swedish right hand driver 83.255.35.43  

H'm. This what you're saying doesn't quite make sense, either. The number of crashes will surely have gone up since 1967. Perhaps you mean the crash rate (per vehicle-kilometre travelled, per thousand vehicles registered, etc.) has declined, which would make sense since that's what's been happening in just about every first-world country over the last four decades. 

Nevertheless, the assertion you call attention to is unsupported, has been for quite some time, and at the very least is questionable. We can remove it from the article unless/until someone cares to add it back with reliable support. — T·C

 Dagen H videos 
If anyone else has found this already and beaten me to it, I'm sorry to be redundant. After a long night of trolling the internet for hours I finally came across the holy grail of Dagen H-related video. Here's the link.

It's from TV Sveriges. That link will take you to the live television coverage from 4.45am to 5.15am. There's yet another clip from 5.15-5.30 and further clips down the right-hand menu to different reports throughout Sweden at different intervals throughout the day. It chronicles the entire switch in immense detail, though be warned that the dialogue is entirely in Swedish (as is the website) so its main function is simply for those of us who draw immense excitement from watching these events transpire. The site also hosts (further down) the news bulletins for the various anniversaries right up to 1997. Again, if this has been posted before, I'm sorry, but for those of you who haven't seen this before, happy viewing.   

Unfortunately, it's been removed. Thanks anyway.
