American Sitcoms - how much is similar to reality?

[BernadetteRostankowskiWolowitz]

Driving while talking on the phone
Driving while looking sideways at the passenger for a long time
Driving after a good few beers
Baby into their own room from day1
Spending hours in coffee houses irrespective of working schedules
Hanging up the phone without saying bye
Hanging up the phone without clarifying where or when they will meet
Eating out 99% of the time

P.s. lighthearted. No dig at all. Be happy to say what the English do/don't do according to tv "norms"

American.

Only two that rang true.
It was like two light beers (DH) and we live in a small town. Would not dare myself - small framed wine-lover. Tried to bike home once. Disaster, but law enforcement not involved .
And regret having baby in my room for 1st and 2nd night. I was booted out after 3rd, despite c-section [hmm}
Really should have taken one night to sleep, BF be damned.

That was a mess, but I'm trusting people understood there are only two of the OP's questions that resonated.

Sleeping with curtains/ blinds open. This is something I’ve noticed on so many American shows/ films. Is it really a thing? They go to bed and not only are the curtains open but the window always is too!

I always sleep with my bedroom window open, and my mother always opened her curtains when it was time to turn the lights out - this is in NZ so not just a US thing.

Is it really easy to get a driving license in the US? In sitcoms they seem to have a few lessons at school, then pop along to the licensing place for test without and pre planning

As an adult who has learned elsewhere it's dead easy to get a US license.
For high school kids it's bit more involved.
They have to pass a written class at school and get a pink slip. Take it to DMV where they take the multi choice test. They they get a provisional and need to take some lessons with a proffesional. There a re minimum number of hours needed and the rest of the time they drove me around while I gripped the passenger seat.
So we did a 2 hour driving lesson to start, then he drove with me a few weeks, then another lesson with the instructor, who would tell him what he needs to work on. Then drive with me for a while again. Final lesson with the instructor who had to either sign him off to take the driving test or reccommend more practise. My lads were signed off and booked a test took about a month to get the test. Then they were out less than 30 minutes and passed. New full license came in the mail and it had a big yellow bit on it saying when they will be 21 to buy alcohol on it.

Amazing to us in the UK to think 20 year olds can’t buy alcohol in the US. Not saying it’s wrong, just hard for us to imagine students. It being able to buy booze!
