<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Through observations I can see that there is a minimum width for lane marking in the UK. I am not sure what the value is, but have seen sections of road where lines end where the road narrows.</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Will try to find an example.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">I am not sure I would want to add a lanes tag where the width falls below this minimum, and would tend to prefer the width tag.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">Whilst following cars, it has occurred to me that knowing their width would be a reasonable yardstick for estimating the width of a road.</p>

I'm quite happy with lanes=n where n is an integer.<br>

I am very happy to assume that a one-way road without lanes=* has only one <br>
lane.<br>
<br>
</div>
<div>
I am also happy to assume that a not-one-way road without lanes=* has two <br>
lanes (one in each direction).<br>
<br>

I am extremely happy to see a width=* tag that I can use in conjunction with <br>
the lane count (even if the lane count is assumed). It tells me the width of <br>
each lane.<br>

A lane count of 1.5 is very confusing. What does it mean? What is the width <br>
of each lane? Is it really 1.5? Should it be 1.55, or 1.4, or 1.6? It's <br>
more useful to tell me width of the road. Then, if there is one lane I can <br>
see maybe it's very wide, or if two lanes I can see maybe they are very <br>
narrow. It's okay to let me assume the number of lanes because the <br>
assumption is safe, and if it's really wrong then someone will tag it <br>
properly later.<br>
<br>
</div>
<div>
In summary, I think simpler is better. A non-integer lane count is useless. <br>
Use the width tag.<br>
<br>
