If there were cars in Equestria...
Big Mac walked down to the car dealership. He was gonna trade his old cart for a car. Unfortunately, the cutie mark crusaders wanted to try the new car, so they rode the cart, adding some weight and making him go a little slower.
"Y'all ready to see the new car? My sister showed me a picture of it. It looks awesome. And Big Mac is gonna take driving classes!" Apple Bloom said to the other crusaders.
"Why do you guys even need a car? You guys are just as good a car." Sweetie Belle asked, admiring how steady Big Mac was going.
"Because, plenty of ponies have switched to cars." Apple Bloom answered.
"True. Plus it'll probably be even faster!" Scootaloo shouted, jumping up for a second, fluttering her wings.
"How will you get it home though?" asked Sweetie Belle, putting her tiny hoof out.
"I guess none of us thought of that." answered Apple Bloom.
The cart came to a stop, and Big Mac motioned for them to get down. The cutie mark crusaders got down and skipped merrily inside the dealership, following Big Macintosh.
The sales pony had white fur, covered in grease stains, and his short black hair was full of gray streaks.
He walked up to the desk and cleared his throat, darting his eyes from left to right, "I-Im here to pick up a car," he stuttered.
The sales-pony looked up at him "Big Macintosh?"
"E'up." Big Mac said sweating.
"What was your car again?"
The red Stalion gulped "A red 2014 Stalion."
"Right over here sir," the sales pony said, going behind a curtain "follow me."
Big Mac motioned for the CMC to stay put, which they did for the most part, although they were still bouncing with joy, then he walked past the curtain.
The car had an old look to it, while still somehow looking brand new. "Here is your brand new car!" the salespony said, handing Big Macintosh the keys.
"Th-thank you," he stuttered as he pulled out a bag of bits and gave them to the salespony, who quickly snatched it up and counted the money.
Big Macintosh walked out to find the Cutie mark crusaders merrily skipping around the room, discussing where they wanted to go with the car. He cleared his throat to get their attention and said "Nope."
The three fillies began pouting "Why?" Apple Bloom pleaded, then she remembered that her brother didn't have a license, "Oooh... Then how are we getting home?..."
The stalion stood outside and waited until a figure came into view. He pointed at the young mare, who was revealed to be Rarity when she got closer. "I'll drive you home," she stated in a sing-song voice.
In the car, the five ponies sat comfortably. For the most part. Someone nearly hit them at a stop sign and Rarity was cursing and swearing while honking on the horn so the kids wouldn't hear, but other than that, she was good. Big Mac observed how she drove and tried to memorize it.
When they got to Sweet apple acres Rarity dropped the keys in Big Mac's right hoof and hopped in the passenger seat "Your turn good sir."
A week later...
"O-okay kids, where to now?" Big Macintosh asked while driving away from the mall.
The girls looked at each other and whispered to one another. "Home," they said in unison. There had been a lot of car wrecks recently due to some unidentified maniac.
Big Macintosh nodded and turned left. Then, BOOM. The maniac struck again, but, no harm done. To the ponies at least. The car was a wreck. They all climbed out to find that the mystery pony's car was also wrecked. Seemed like the masked pony was too preoccupied trying to start the car to notice that there were police sirens blaring. Or that their victims were getting away.
A police pony with a bushy brown mustache pulled them out of the car and pulled their mask off to reveal - Pinkie Pie! But not just Pinkie Pie, her hair was strait and her eyes looked deadly.
"I'll get you for this!" she yelled before entering the police car.
A police pony walked up to Big Macintosh "Thank you for catching the maniac. If you'd like we'll pay to repair your car."
He looked around "Nope," after the danger of today, he didn't think it'd be wise. He gathered the kids and walked them home. The sun was setting. One thought crossed the large stallion's mind: I hate cars
The end!
