I can't turn ESC off on my car but I can turn traction control off. In any case you can get the Veloster very sideways without ESC intervening so ESC fairly passive. For drivers who drive all wrong and end up borderline understeering off the road like the OP, then for sure ESC can give you a false sense of security, and when you overstep what ESC can correct then you will have a very big smash! We have growing road fatality stats in Australia which indicate this.
If a car understeers then lift off, and it will grip at the front and maybe go a bit sideways which is alright because you can correct a slide if you have front wheel grip. If you coax it sideways like I do then keep your foot in it and gently correct the steering (lifting off will cause a spin, as will correcting less than gently).
I think all car drivers should ride motorcycles for 6 months, then they will learn all about cornering techniques or end up in hospital all smashed up (or worse). I see so many drivers turning-in early, braking while turning in, braking harder while turning in (braking and turning will coax terminal understeer out of any car). In fact I hardly ever see any drivers do it right! Brake in a straight line, then turn and clip the apex middle to late while under power, and power gradually harder out of the curve. How hard is that?
