All-Electronic Tolling is making that a thing of the past. My brother-in-law actually had that job for about a month as a teenager, but quit due to boredom (this was 30 years ago)...they were quite proud of his 99.5% success ratio.
@RoadRunner36 Your career will depend on how much you're willing to invest in school, how much you want to be in a classroom, how much patience you have, and/or how much you own in tools. A lot of it has to do with personal drive and motivation, but the biggest help if you live in and around some variety of motoring activities.
- Mechanic
Obviously the one with the greatest longevity and most in-need. You definitely start out in the shallow end of pay, and your investment in tools and school isn't cheap. You will have to scrap for everything, and be at the mercy of others somewhat equally motivated.
- Engineering (mechanical)
Must be great at math and physics. School isn't cheap, and it's also an intensive amount in time at university. There's no guarantee you'll land a job in the automotive world, but it's nice to keep your options open, and a degree is quite a handy item in the atelier.
- Salesman / Service Advisor
No school necessary, basic auto knowledge helps a bit, more is better. If you can sell, wonderful! If you can't...you'll struggle. Selling isn't an exact art, but knowing the basics, knowing your products, meeting the customer at the level of their expectations (and greater) works out a lot. You can get started right out of high school.
- Civil Engineer
How about planning and designing roads and the like? You do have to be good with math, sciences, and at the beginning stages of your career, you'll get your hands (and extremities) dirty. Also, it's rather slow-going; but your results will physically exist for decades.
- Designer
Art school! Nobody starts out fresh into designing Porsches, so you start out making trim pieces for Holden. Auto Design is also about cohesive singular items appearing as one, so you work in a team. Expect rejection, but sometimes all it takes is one hit to launch your career.
- Racing driver
Oh, don't we all wish.
