Why would you not push too hard when training fasted...especially if you're only doing up to an hour or so? I do virtually all my training first thing in the morning, and then cycle to work before having breakfast! Would it not also be the case that training in the morning after having had a decent dinner the night before isn't quite the same as training fasted?
TL;DR I've no answers for you, only questions!

The downside to training fasted is something along the lines of:
Training fueled means you perform at a higher level than if you were fasted/not-fueled. So, if you don't ride as hard, you don't adapt to a higher training intensity, you're not getting as fast.Also, some evidence that training fueled, especially in longer stuff, helps avoid colds and other ailments because less cortisol (stress hormone) is produced when fed vs. fasted.

I'd read somewhere that pushing too hard means you'll just burn through any residual stored glycogen and whatnot and then just munch through your lovely muscles - and like @hippy says going too long or hard when fasted could make you ill. But i don't know if taht counts when less than an hour?
Also, i reckon riding in that 'sweetspot' area, which is hard but kind of not hard, should be ok as it's not super intense? I wouldn't fancy doing short and brutal intervals with nothing in the tank
Like you @SCS, i just smash down a banana and whey smoothie after an early session then ride too work (only 25 mins), before my bucket of porridge.

Early morning turbo training question approaching -
Although i wake up in dread on these mornings, I tend to do a lot of my turbo stuff early in the morning before work. As i'm usually on the turbo within 40ish minutes of getting out of bed, I don't eat before as I can't imagine I'd actually have digested it in time so it seems pointless- i just have a good breakfast after.
I know that you're not supposed to push too hard when training fasted, but i always end up kind of ignoring this and do around 40-50 mins at c.90% FTP as a kind of 'base' workout (split into 15/20ish minute intervals. Is this bad?
To those of you that do pre-work turbo, do you eat beforehand? What kind of workouts do you do?
