There's no money in cheap cars, anymore. Pricing cars at $25,000 serves no function but to lose money, anyone who can afford to pay $25,000 for a new car can afford to pay $35,000, or $45,000.
"Through the haze of production cuts and supply-chain snafus, some automakers are discovering they can deliver better results without stockpiling vehicles or padding sales volumes with low-priced, low-margin models."
No money in cheap microcontroller either. The $3 to $5 micros are all out of stock or long lead time. So, i have to go with $10 to $15 chips with 1M flash to build some LED blinkers.
Heard of transistors, resistors, and capacitors? Relaxation oscillators? (ducking)

Even the attiny85 is getting scarce.
But need ADC to scan signal, and USB for logging. Unfortunately, can't do both currently with STM32F411 ($10), might need STM32F649 ($15).
I'm paying up to $60 for a $3 CODEC because the factory burned down. A part that is still in full production with lead times of over a year is only going for 3x it's regular price.
Such is life in times of allocation.
To just blink some LEDs the attiny84 is a great value right now, usually they're more expensive. only 82 cents in singles.
It has 10 bit ADCs and you can bit-bash USB comms from one so long as you don't expect miracles. Clock it at 18 or 20 MHz using an external crystal for best results:
