My family used to raise chickens when I was a kid. The chickens were free-range (only house for like a mile), but they had a coop to eat and nest in, which we shut every night. When getting new chickens to add to the flock (neighbor has too many, etc), we'd keep them in a "chicken tractor" for a few weeks (basically a small, mobile chicken coop). I guess that gave everyone time to get used to each other's smells or something, because the few times we didn't do that the new chickens would get pecked in the head by the locals, and once the locals realize that the new ones taste like blood it's pretty much over for the new chickens.
Many cars and trucks don't even have a tach. Older Ford focus's don't, they just have a shift light. I used to drive a 70s Ford ranger that had neither. Don't get me wrong I wish it did, but it's only a nice-to-have for regular driving. Shifting off sound is fine, but it's not just sound, it's the vibrations in your seat, how the engine reacts to gas pedal inputs, etc. I only look at the tach when I need to downshift to pass.
I've never driven a car that couldn't do this, and I've driven at least a dozen manual transmission cars and trucks, all gas. Hell my beater right now doesn't have first gear, and I have no problems starting in second just idling. You just need to be really slow and attentive to your rpms. Not that you should always start rolling like this, but I agree with the comment above that it's an excellent learning exercise. I always start with this one when I teach other people how to drive stick with great success, and I wish that I started with this exercise when I was learning.
That's me, I don't really care where the maple syrup came from as long as it's real
