By bus? By train? 'course the same laws of physics that say a ~1.5t car does more damage than a ~100kg bicycle might also have something to say about a ~10t bus. And remind me what a train weighs?

As do many non-hybrids. Although, having said that, my car engine barely ever idles during my commute.

You seem to be forgetting the primary national markets of the current hybrids. And, of course, the "Is it or isn't it" over diesel vs petrol emissions.

To answer those points directly: Regenerative braking simply 'reclaims' some of the electricity already used. An idling petrol / diesel engine uses barely any fuel at all - drivers who are concerned about the half thimble of fuel they might waste in 5 minutes of idling can use the little key just next to the steering wheel - a simple turn and the engine uses no fuel at all! Another point always omitted from these discussions is that people don't realise that electric car batteries have a finite lifetime (is it 2-3 years?) and can't just be thrown away like torch batteries. New batteries are expensive and have to be made at smokey factories and distributed using smelly lorries etc etc.

Well we all get stuck in traffic jams occasionally and an idling engine is doing zero mpg. BUt yes , non hybrids can do start-stop too but they can't trickle along on electric power that may have come via the regen braking. >> Though if they had diesel engines instead of petrol they'd be a lot >> more efficient than they are at the moment. > >You seem to be forgetting the primary national markets of the current >hybrids. And, of course, the "Is it or isn't it" over diesel vs petrol >emissions. Yes I know the yanks hate diesels and I can understand why. But going purely by CO2 emmissions and mpg diesel beats petrol every time. B2003

By train? Unfortunately, not an option - they pollute the environment, take bloody ages and smell! Bus would take hours and about 3 changes (maybe 4) - my work isn't on a bus route and is in the next region. I looked into the train - I have to leave before 5am to get there for 9:30am. Plus I have to add a 20 minute walk at 1 end and a 30 minute walk at the other end. > 'course the same laws of physics that say a ~1.5t car does more damage > than a ~100kg bicycle might also have something to say about a ~10t bus. > And remind me what a train weighs? |
