eyesup......
I learned flying on a TMG back in 1983, got my PPL for it in 1984. I then turned to Pipers, etc. because I had 2 kids and hoped to take my kids along for flights. I was really addicted to flying and had some really nice flights. In March this year I survived my (only) serious accident...in a TMG. As is often the case, the PIC made some mistake...... he was a very experienced pilot (82 yrs. old with 8000+ hours)...... he did NOT survive (and I am now in a wheel chair).
Don't be so afraid! Your drive to the airfield is more dangerous. Do what you want and learn all you can! Your best safety insurance is knowledge!
