Can he change his mind?

Tell him that you are worried about him and that you would be much more at ease if he travelled in a safer vehicle.

All you can do is tell him how you really feel, explain to him that you are aware and scared that he could get seriously hurt, and you do not want that to happen.

Then you may make some suggestions as to a type sports car or suv you may think he will like. He amy be willing to compromise or may not-who know's if you don't ask.

Explain to him your concerns on riding it with him... If you are really terrified, I am sure he will respect your wishes and not take you on it.

As for telling him what to purchase to drive that is a totally other thing.

Some guys think it is truly macho to have a bike and it pumps up their egoes.

It is also a power thing and they like the feeling of something that you are in complete control of.

This is something he will have to get out of his system.

Hopefully if he gets a bike he will be careful...

Your hands are tied.... Hope for the best...

Tell him how you feel about it. It will be better then trying to trick him into doing what you want him to do. Men hate that. He may be more inclined to buy a car if he knows it scares you this much. Be honest!

Tell him that you'd like to go places with out having to check your hair when you get there. Mention the back seats of the car, and what you'd like to do with him ;-)

its useless dont even bother trying
