I think 1/4 of all designers want to do cars. Once you meet some people though and figure out the numbers, you realize it’s doubtful. There are 4 really good transport design programs in the world graduating about 80 students a year. I think the industry has 40 entry level openings a year. That means if you went to a state school like me, you have to impress more than 40 people that studied just transport design at specialized schools. Not impossible, but difficult.
The same thing goes for design though. I think only 4 of my graduating class are still in ID fifteen years on. I’m sure that half the class never had a full time design job. Sometimes I think it’s a miracle I’ve managed to sustain this long!
