Engine idling
There was something on tv a few weeks ago about school children telling the waiting mums to turn their engines off while they are waiting.
I've also noticed quite a few times, drivers get in their car and first thing they do is turn the engine on. Then they faf about for seeming ages (probably only minutes) before eventually pulling away.Today dad was riding his mobility scooter on the path and wanted to go onto the road as it was a less busy one. About 50 metres ahead we saw a man get into his car and heard the engine start. I said to dad, "Just wait for him to go, then you can go". We waited for several minutes. F... knows what he was doing. Told dad to go anyway. Lost patience waiting for him.
