Yes, I agree, mostly. The main corridors of East Cleveland are well served. 2 x 5, 2 x X4. The 5a and X3 do the Lingdale offshoot and commercially and viably that has to be enough given passenger usage. 
The 1 and 2 services trundling around the lanes are simply giving the Stagecoach drivers an easy shift and then,being serious, costing money the area can't afford. Usage is poor and you simply can't justify this for the odd few people that want to go to Asda. All the rest have made other arrangements and aren't coming back.
Investing in electric fleet to serve the routes I talked about can't be justified. Sadly we live in a commercially driven situation unless you hapoen to be in Moorsholm which has a regular service no buggar uses!!
