That's your opinion, just like I have mine, not sure why you feel the need to call it narrow minded.
I'm not old enough to have followed speedway back in the 70/80s, so I don't know what it was like back then to compare, but it's still broadly the same sport as now.
Electric speedway would be completely different. I do enjoy the noise I have to say. The smell has pretty much gone in recent years. I just enjoy that speedway is pretty much a raw motorsport and I'd rather it stayed that way. Maybe I'd change my opinion if/when it happens but I'm not sure.
