As a Bus Driver, we also need proper access to bus stops. The various councils across the country have spent OUR money raising kerbstones, so that buses with wheelchairs/buggies,the elderly & infirm can access & exit the bus more easily. All the buses I drive will have a ramp available - more often than not however, simply lowering the front suspension is sufficient.
Yet when pillocks park in bus stops, it can make this access difficult, and sometimes impossible.
p.s. noticed the absence of the yellow rover today, however, an orange transit van was parked 20 yards further up!!
