Please let me know the difference between those two words above.
I could find both "automobile accident" and "automotive accident" in the dictionary. It seems almost the same.
Any difference in usage? Can I say both "automobile industory" and "automotive industory" in the same context?
Automobile- can be an adjective or a noun, while 'automtive' is only an adjective. For the industry, both are used, but the results from Google suggest that 'automotive' is more common:
12,800,000 for "automotive industry"
4,520,000 for "automobile industry"
