i think its unrealistic in movies when people hot wire a car , like if i were to try that i'd pull out wires from the under the dash and it would

Older cars are easy to hotwire but no chance with more recent cars.

will hot wiring unlock a steering wheel?

Pretty well impossible now, but unfortunately some manufacturers have become so besotted with gadgets like radio-controlled door and ignition locks that the really determined car-thief gangs have developed eavesdropping equipment to detect the right code for the car worth them stealing.

There’s so much more with movies..
a cop can go on a hour long kill spree.
And not get stood down pending an internal investigation?
Nope. Right back on the streets to chase more bad guys..

I've seen someone get into a car and disable the alarm within 30seconds. Then the customer turned up with the key, just as we were about to move the car, and said "oh, great to see my car is easy to steal" If somebody does something alot they get fast at it.

zero chance of hotwiring anything built in the last 30-40 years; let alone slim jiming one to unlock doors, newer cars have box built around mechanism to prevent it, and most won't work at all on anything with power locks

Or how they unlock their handcuffs

Almost everything in movies is wrong. Everything is rushed and badly thought out.

Lol or when they find keys in the sun blinds or underneath the car.

It's just a device plot. It hasn't been a very fast way to steal a car since the 1950s anyway.

The locks are always made of cheap pot metal and a couple tools could turn that ignition lock in 2 seconds.

Now that they keep using electronic methods it's even easier to just record someone's beacon signal and clone it.

My ex could do that

Always funny. My old car would instantly shut down with the right key. Yes, you can bypass this, but it involves taking apart the steering column, fiddling with the insides, and outright changing the ignition computer. Probably not worth it.

old cars were less complicated i think.. nowadays they clone keys or something
