I'll just keep the comments for a record - we can see if anything changes in the next five years.

> I see 海を走る

Well, that's obviously not the sort of thing I was considering ;-)

I'll see if I can pick out a few of the most plausible looking and get some second opinions as to how weird they look.  It might be worth a [note] on the sense.

街中で自転車を走るなら、ファッショナブルに決めたいもの。
* That's pretty straight forward.

車を走る事5分足らずで、「くーんくーん」泣かれ、仕方がなく膝に抱っこ。
また、車を走る事15分で、嘔吐され、膝は吐いたもので、ぐちゃぐちゃ状態。
* Two for the price of one

さらに車を走ると、思わず息を飲む光景を見て思わず車を止めました。
* Another clear cut case.

丹波を後に、車を走ること？分・・・・
* Looks pretty confused to me.

So that's about 4 true positives from the first 40 Yahoo hits.  Giving 2,300 as a 'guess' as to how many times it's actually (mistakenly or not) been used in as a 'vt'.

Maybe something like [note="occasional use as a transitive verb (e.g. 車を走る) is not accepted as good usage"]
?  I'll see if I get any interesting feedback.

I've noticed quite a few places where the final 道 is dropped from names like 宮崎自動車道.

Eijiro has a handful of XXを走る examples. I see 海を走る
gets 60k Yahoots, but some are prenominal.
I suspect it's not really mainline use of 走る, and perhaps the "vi" should stay there are the general rule.

looks like it.  but i wonder if it's considered correct usage or not

I note that 車を走る has 23,000 Yahoo hits. Much less than 車で走る (2,520,000), but they have different meanings. Any opinion on whether the vi should be removed from [2]?
