There is a lot of garbage in OSM due to those creating routers being
too lazy to write a few lines of code, or even use common sense.<br>
<br>
However, in this case I believe it's other contributors who think,
for reasons that escape me, routers require it.<br>
<br>
Routing software must be of a poor standard if it returns the
commuter to the roundabout after just 10 metres or so after leaving
it.<br>
<br>
I partially agree with Phil's suggestion that they're harmless, if
turn restrictions are by themselves. However if there are multiple
at one junction it can become error prone. Any that aren't required
are best removed.<br>

<div>There seems to be a predilection for adding turn
restrictions , either no right rurns or no U turns at the exit
flares of roundabouts to prevent turning back into the entry
flares where there are no explicit signed restrictions. I
suspect this is "rendering for routers". Do routers actually
need this data? I'm tempted just to delete them all wherever
I meet them, but I suspect there are thousands of them and
there'll be howls of complaint. <br>
