When the remains of Tim Kwon's car slides up to the barrier, one of the tires hits the barrier a couple of seconds later. When it does, the barrier bounces away and then back. This barrier would be either a concrete Jersey barrier or the portable plastic Jersey barriers which are filled with water once in place. Neither would move and rock from the light impact of a rolling tire as they are too heavy and designed to stop or deflect a car, which is about 30 times the weight of the tire and wheel, so this is either a prop "concrete" barrier or a plastic one that was not filled with water.
When we first see Tim Kwon, he's driving a Tesla Model X. At one point there is a shot of his feet on the car's pedals. This could have been a stock shot of any car, but it was still a shot of a normal car's pedal box (steering column above, pedals hanging down). After Deacon rips the car to pieces, all that's left is Kwon sitting in the car seat, on a small piece of chassis, with part of the steering column and steering wheel. However now the steering column is between Kwon's feet. Modern cars always have the steering column above the driver's legs and feet, not in between them.
