Auto- is a prefix that works in two directions at once, which is rare and useful.
Automated tutoring is where educational technology actually landed: adaptive practice, instant feedback, and language models that can explain a problem step by step. The market is large, well funded and moving fast, with every descriptive name taken years ago.
Automotive tutoring is the narrower reading: mechanic training, driving instruction, and technical education for the vehicle trades. That’s a real vocational sector with certification requirements and a skills shortage.
The ambiguity resolves instantly from the site itself, so it costs nothing in practice while widening the buyer pool considerably.
