You will use more fuel and cause more wear in the long term by manually revving the engine. The whole point of the auto gearbox is to take human intervention out of the equation and in the case f skyactive, achieve lower fuel consumption and lower emissions. If you choose to override those settings then you undo all the good that the settings are intending to achieve. It is the intention of all vehicle manufacturers to do away with manual transmissions in the same way they did away with manual chokes so that it will eventually not be possible to override pre mapped control. Toyota already have a timing plan for that process.
My Mazda automatic is the best I've ever had, changing up early to get the best out of my diesel's low end torque. I also had a CX5 rental last year and was extremely impressed by how it did similar unlike autos of the past which seemed very random at times. There is a lot of logic and common sense to the mapping of these boxes and other than a little fun or a planned overtake, I see little need to interfere.
Snoogie. I know you are probably being a little flippant and half joking buddy, but telling people to panic at the sight of the engine check light is probably not a good idea.
