Yes. A few points.
Real, better cars get destroyed all the time (for instance).
The DeLorean has always been known as a fairly weak car. Its construction and crash survivability is pretty low. It had a Fiberglass chassis when most cars were still fully metal. Remember in the previous movie, Marty wanted the Doc to block ...
No, the car would probably not explode.
Cars get hit by trains all the time in reality. In general, a lot of the momentum of the train goes into moving the car -- either pushing it along the tracks or hurling it to one side, depending on the situation.
In reality, what most likely would have happened in BTTF is the Deloran would have been hurled off to one ...
He appears to have inherited it.
When explaining to Marty where the flux capacitor came from
I had a revelation! A vision! A picture in my head! A picture of this! This is what makes time travel possible: the flux capacitor! It's taken me nearly thirty years and my entire family fortune to realize the vision of that day
I originally thought that this was completely possible, but after looking into how they achieved the effect, I am convinced that in real life, the DeLorean would have been crushed and would have lost a few parts, but not disintegrate to the degree that the movie DeLorean does.
This page mentions in the "Future Facts" section that the DeLorean that you see ...
The doors and furniture are completely different. In the movies, the Palace Saloon is in Hill Valley, California. The Django saloon is in Texas. From IMDB:
When Django and Dr. Schultz are in Daughtrey, Texas (near the beginning of the film), the saloon they are in is called "Minnesota Clay's Saloon". Minnesota Clay (1964) is the name of Western film ...
The problem is that you are comparing technically different time-machines.
Over the course of the trilogy the DeLorean was changed 2 times.
So we have:
The original powered by plutonium (1985)
Upgraded version powered by Mr. Fusion (2015)
MacGyver version with a vacuum control unit (1955/1885)
Versions 1 and 2 behave the same way:
Reach 88 mph > Flux ...
There was no plot explanation. There is much speculation (and I highly doubt this is going to show up in an interview or in DVD commentary since it should have been spotted by the Continuity Editor) that the actor needed to go to the bathroom. If you have kids in the 6-8 age range, which is approximately how old Dannel Evans was at the time, you know that ...
There's a lot of information regarding backstory in the newspaper clippings that cover Doc's walls in the opening credit sequence of the first film. Pretty sure there were clues there as well as Doc's reference to his family fortune. You'll need a big TV though!
In the third movie the time circuits were replaced with analog 1955 parts. Presumably this analog time circuit doesn't have the clean "on-off" functionality as the original version built into a microchip. It makes sense that it's function would slowly ramp up. You can also see that the flux capacitor slowly brightens instead of immediately lighting up like ...
