日本でも、OSMに対する懸念として正確さや信頼性は、
攻撃とまでは言わずとも、よく聞かれるところだと思います。
このあたり、みなさんのお考えやご意見をお聞かせ頂ければ幸いです。

その正確さと信頼性をTomTomのマップと比較するものです。
1.OSMは道路のカバー率がTomTomより低く、車道と歩道がごっちゃになっている。
これは、きちんと入れてない場所がそれこそたくさんあるので
しょうがないでしょう。ただ、徐々に整備されていくかと。
10年経てばかなり整備されるのではないかなあ。
2.OSMは攻撃に対してもオープンであり、過去に一方通行の方向を書き換えられたこともあった。
としです。
まぁ、「いつかこんな日も来るだろう」と思っていました。
個人的には、地図ベンダーやカーナビベンダーが、OSM の存在に
注目していると言う事で、それだけ認知が進んでいると、前向きに

Gert, the same problems you attribute to OSM are valid for TomTom
(TeleAtlas) as well.
But don't believe me, I provide OSM Garmin maps for almost 5 years now,
so I'm probably 'too forgiving with my baby'. It's the users of these
maps that disagree with you.
A few recent quotes from OSM
I recently travelled in Bosnia and Herzegovina and Montenegro thanks to the
maps of Lambertus (OSM). We never got lost and I only had to make some few
coorections (roundabouts, etc) and add a road. we would never had found our
way without OSM and the good work of Lambertus.

Well, probably one of the very positive effects from OSM is the fact that when
we start mapping something, the closed-source mappers follow suit. The fact that
Google needs to add gimmicks like kajak routing across the pacific to beat us
says enough.
It's a win-win situation.

To be honest, if a road has no classification, and is made of mud and gravel,
it's a track... If it's an official road in some way, then clearly it is
classified ;)

Well (at the risk of stating the bleeding obvious) we can actually see

actually get routed
