There's not a simple relationship between cost of the end product and the budget for developing safety-critical systems. There are only ~1600 777s ever built. The development costs for automotive systems are amortized over millions of units. I have no idea what the budgets actually are, and it's fine if you don't trust certain kinds of automation in cars. In fact my 2020 Toyota with lane-keeping assistance tried to drive me off the freeway at 80mph three times last week. (I probably should have stopped trying it after the second time, but I was kind of morbidly fascinated at that point. As it steered me firmly towards the grassy median, it also started beeping urgently to tell me that it wasn't a good idea.)
