Factual error: When the house explodes there is a massive explosion and fireball that creates a pressure wave strong enough to send Brian flying into the van. However not a single window breaks on the houses just feet from the explosion.
Factual error: Brian, when confronted with the drone for the first time, goes "old school" by driving under the lorry trailer. However, trailers don't have anywhere near enough ground clearance for that car to fit, no matter how much the car suspension was lowered. It only works here because the trailer has been artificially lifted.
