One more point then I really am going to move on
The blisters are not at all directional, so how does someone who is visually impaired tell the difference between the approach to a crossing & a strip which is laid at right angles across the pavement?
You put your kerbside up (at the bus stop)
You put your kerbside down (at the crossing)
Up, down, up, down
Shake yourself around (with tactile paving)
That’s what it's all about
