Majority of the civilized world uses smaller vehicles than a crown vic with great success.
I suggest you do a little research on that. The US is BY FAR way ahead of the rest of the civilized on Emergency Trama. FAR FAR ahead of the rest of the world. The US pioneered the on-site trama care…which many countries are now just adopting. Most other countries just grab and go (we use to do that 30 years ago). Now our EMT’s arrive and provide life saving care and stabilize the patient before transport. Try carrying all equipment needed for true EMT care in a Crown Vic!! You’ll need a trailer or a roof-rack.
