I saw some of the action from the Sheffield meeting in Luke Killeen's Vlog, and it was clear you couldn't just "howl" into the bends at full gas, sideways blocking the track, meaning the rider behind couldn't pass, but just did the same thing...
Meaning, as often happens at most tracks, four riders in procession, equidistant apart...
From the action I watched in the Sheffield match, the riders had to go around the bends more circumspect given the level of grip they were getting, hence more mistakes and opportunities were available to be had...
Hence, the racing was decent...
With so little actually riding on the outcome of a any UK Speedway meeting, you would think the promoters would 100% focus on ensuring that the actual entertainment level, both on and off track, encourages people to keep attending wouldn't you...?
