From your data it appears that you are basically an automobile engineer engaged in teaching work related to same field. Teaching job is more and less theoretical in nature but it gives a good insight of the automobile engineering and with some practical exposure one can come up to the expectations of the industrial world.
If you are serious to change your line from teaching to technical side then there are certain considerations and deliberations to be done before taking that decision.
The first and foremost is whether you have an interest and liking for the technical or industrial side of automobile industry or it is only the stagnation in your teaching job and this aspiration is coming in your wandering thoughts time and again. Why I am asking this blunt but important question is because we generally work hard and dedicate our efforts only in our interest areas. You can go through the various case studies and case histories about the successful people in this world and you will find this fundamental element there.
Anyway I assume that you have ample interest and curiosities in the technical side and you are ready to take up the challenges. So I will go ahead and suggest some job roles where you can try your luck to enter the industry and then with sustained efforts and hard work come up to the expectations of the management for further growth in the area.
Today, the automobile industry offers many challenging and interesting roles to skilled and experienced persons. Some of the prominent ones are -
1. Designing, development and manufacturing of vehicles.
2. Creating blueprint of vehicles and its components.
3. Maintenance and Services Engineers in automobile workshops, aircraft industries, aviation, marine vessels, and diesel power stations.
4. Administrative and training jobs related to the automobile industry.
I will like to draw you attention to the role at serial number 4 above where you have the experience and expertise. Just think of it.
So, there are opportunities as the auto sector is poised for growth. The fossil fuels are going to be depleted soon and all the vehicles will be replaced by the electrical ones and it is in that reference that one has to concentrate and focus in the electrical vehicle area also.
Knowledge is power.
